    摘要: A process for the direct and regioselective functionalization of phenothiazine which allows one to introduce an SH group in position 2, said process comprising the sulfination or sulfonation of the phenothiazine N-protected with an alkoxycarbonyl, an alkylsulfonyl or an arylsulfonyl group, the reduction of the produce obtained to give the N-protected 2-mercapto-phenothiazine, and the deprotection of the nitrogen atom. The thus-obtained 2-mercapto-phenothiazine is an important intermediate for the preparation of pharmacological active compounds.
