Sulforidazine (Imagotan, Psychoson, Inofal) a typical antipsychotic and a metabolite of thioridazine; it and mesoridazine are more potent than the parent compound, whose pharmacological effects are believed by some to be largely due to its metabolism into sulforidazine and mesoridazine.[1]
Synthesis
Synthesis of sulforidazine
Sulforidazine can be synthesized starting 2-bromo-2'-amino-4'-methylsulfonyl-diphenyl sulfide (1).[2][3][4] Acetylation produces 2-bromo-2'-acetamino-4'-methylsulphonyl diphenylsulfide (2), which is then alkylated with 2-(2-chloroethyl)-1-methylpiperidine (3). Deacylation followed by a copper-catalyzed ring-formation reaction produces sulforidazine.
