Dixyrazine, also known as dixypazin (oxalate), sold under the brand names Ansiolene, Esocalm, Esucos, Metronal, and Roscal, is a typical antipsychotic of the phenothiazine group described as a neuroleptic and antihistamine.{{cite book|author=J. Elks|title=The Dictionary of Drugs: Chemical Data: Chemical Data, Structures and Bibliographies|url=https://books.google.com/books?id=0vXTBwAAQBAJ&pg=PA462|date=14 November 2014|publisher=Springer|isbn=978-1-4757-2085-3|pages=462–}} It was first introduced in Germany in 1969. It is used as a neuroleptic, anxiolytic, and antihistamine in doses between 12.5 and 75 mg a day.

Synthesis

File:Dixyrazine synthesis.svg

Sodamide alkylation of phenothiazine (1) with 1-bromo-3-chloro-2-methylpropane (2) gives 10-(3-Chloro-2-methylpropyl)phenothiazine (3).[https://pharmaceutical-substances.thieme.com/ps/search-results?docUri=KD-04-0132 Thieme]Henri Morren, {{Cite patent|GB861420}} (1961). Completion of the sidechain by alkylation with 1-[2-(2-hydroxyethoxy)ethyl]piperazine (4) and displacement of the halogen completes the synthesis of dixyrazine (5).
