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.[1] 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
Synthesis of dixyrazine

Sodamide alkylation of phenothiazine (1) with 1-bromo-3-chloro-2-methylpropane (2) gives 10-(3-Chloro-2-methylpropyl)phenothiazine (3).[2][3] 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).
