Thiopropazate (Artalan, Dartal, Dartalan, Dartan) is a typical antipsychotic of the phenothiazine class.^[1] It is a prodrug to perphenazine.

Thiopropazate is manufactured by Searle (US, UK) & Boehringer Mannheim (Germany)^[2] Thiopropazate is sold by Chembase, AAA Chemistry, ZINC, AKos Consulting & Solutions, Boc Sciences, ChemFrog, and ChemMol^[3]

Synthesis

The alkylation of 2-chloro-10-(3-chloropropyl)phenothiazine [2765-59-5] (1) with Piperazine (2) gives N-Desmethylprochlorperazine [40323-85-1] (3). Further alkylation with 2-Bromoethyl acetate [927-68-4] (4) gives Thiopropazate (5).
