Butaperazine Synthesis
Butaperazine (Repoise, Tyrylen) is a typical antipsychotic of the phenothiazine class. It was approved in 1967, and possibly discontinued in the 1980s. Synthesis Butaperazine can be synthesized starting from 2-butyrylphenothiazine (1).Dr Ulrich Hoerlein, Dr Klaus-Heinz Risse, Dr Wolfgang Wirth, (1961 to Bayer Ag). It is prepared in a manner that is comparable to the method used in the synthesis of propiomazine and propiopromazine. The phenothiazine is alkylated with 1-(γ-chloropropyl)-4-methylpiperazine (2), which is prepared in the conventional way by alkylating 1-methylpiperazine with 1-Bromo-3-chloropropane, 1-bromo-3-chloropropane.

Diário Oficial Da União
The ''Diário Oficial da União'' (literally ''Official Diary of the Union''), abbreviated DOU, is the government gazette, official gazette of the Federal Government of Brazil, Federal Government of Brazil. It is published since 1 October 1862 and was created via the Imperial Decree 1,177 of its 9 September as the ''Official Journal of the Empire of Brazil''. Its current name was adopted after Brazil became a federal republic, and the "Union" came into being as the legal personality of the new federal government. The official journal is published by the Imprensa Nacional, Brazilian National Press. Though the journal has been published since 1862, it had many predecessors, as follows: # Gazeta do Rio de Janeiro (10/9/1808 – 29.12.1821) # Gazeta do Rio (1/1/1822 – 31/12/1822) # Diário do Governo (2/1/1823 – 28/6/1833) # Diário Fluminense (21/5/1824 – 24/4/1831) # Correio Oficial (1/7/1833 – 30/6/1836) e (2/1/1830 – 30/12/1840) # Without proper journal (31/12/1840 – ...

Typical Antipsychotic
Typical antipsychotics (also known as major tranquilizers, and first generation antipsychotics) are a class of antipsychotic drugs first developed in the 1950s and used to treat psychosis (in particular, schizophrenia). Typical antipsychotics may also be used for the treatment of acute mania, agitation, and other conditions. The first typical antipsychotics to come into medical use were the phenothiazines, namely chlorpromazine which was discovered serendipitously. Another prominent grouping of antipsychotics are the butyrophenones, an example of which is haloperidol. The newer, second-generation antipsychotics, also known as atypical antipsychotics, have largely supplanted the use of typical antipsychotics as first-line agents due to the higher risk of movement disorders with typical antipsychotics. Both generations of medication tend to block receptors in the brain's dopamine pathways, but atypicals at the time of marketing were claimed to differ from typical antipsychoti ...

Phenothiazine
Phenothiazine, abbreviated PTZ, is an organic compound that has the formula S(C6H4)2NH and is related to the thiazine-class of heterocyclic compounds. Derivatives of phenothiazine are highly bioactive and have widespread use and rich history. The derivatives chlorpromazine and promethazine revolutionized the fields of psychiatry and allergy treatment, respectively. An earlier derivative, methylene blue, was one of the first antimalarial drugs, and derivatives of phenothiazine are currently under investigation as possible anti-infective drugs. Phenothiazine is a prototypical pharmaceutical lead structure in medicinal chemistry. Uses Phenothiazine itself is only of theoretical interest, but derivatives of it revolutionized psychiatry, other fields of medicine, and pest management. Other derivatives have been studied for possible use in advanced batteries and fuel cells. Phenothiazine-derived drugs In 1876, methylene blue, a derivative of phenothiazine, was synthesized by H ...

Propiomazine
Propiomazine, sold under the brand name Propavan among others, is an antihistamine which is used to treat insomnia and to produce sedation and relieve anxiety before or during surgery or other procedures and in combination with analgesics as well as during labor. Propiomazine is a phenothiazine, but is not used therapeutically as a neuroleptic because it does not block dopamine receptors well. Medical uses Propiomazine has been used in the treatment of insomnia. Side effects Drowsiness is a usual side effect. Rare, serious side effects include convulsions (seizures); difficult or unusually fast breathing; fast or irregular heartbeat or pulse; fever (high); high or low blood pressure; loss of bladder control; muscle stiffness (severe); unusual increase in sweating; unusually pale skin; and unusual tiredness or weakness. Pharmacology Pharmacodynamics Propiomazine is an antagonist of the dopamine D1, D2, and D4 receptors, the serotonin 5-HT2A and 5-HT2C receptors, the muscar ...

1-methylpiperazine
''N''-Methylpiperazine is a heterocyclic organic compound. Uses ''N''-Methylpiperazine is a common building block used in organic synthesis. For example, ''N''-methylpiperazine is used in the manufacture of various pharmaceutical drugs including cyclizine, meclizine, and sildenafil. The lithium salt, lithium ''N''-methylpiperazide, is used as a reagent in organic synthesis for protection of aryl aldehydes. Synthesis Industrially, ''N''-methylpiperazine is produced by reacting diethanolamine and methylamine Methylamine, also known as methanamine, is an organic compound with a formula of . This colorless gas is a derivative of ammonia, but with one hydrogen atom being replaced by a methyl group. It is the simplest primary amine. Methylamine is sold ... at 250 bar and 200 °C.

1-Bromo-3-chloropropane
1-Bromo-3-chloropropane is an organohalogen compound with the formula Br(CH2)3Cl. It is a colorless liquid, produced by free-radical addition of hydrogen bromide to allyl chloride. It is used as an alkylating agent Alkylation is a chemical reaction that entails transfer of an alkyl group. The alkyl group may be transferred as an alkyl carbocation, a free radical, a carbanion, or a carbene (or their equivalents). Alkylating agents are reagents for effecting ... to install the –(CH2)3Cl and –(CH2)3– groups. For example, it is a precursor to 4-chlorobutyronitrile.
