合成路线1
该中间体在本合成路线中的序号：(II)The oxidation of 7-chloro-5-hydroxy-2,3-dihydro-1-benzothiepin (I) with H2O2 in acetic acid - water gives 7-chloro-5-hydroxy-2,3-dihydro-1-benzothiepin-1,1-dioxide (II), which by reaction with pyrrolidine (III) and p-toluenesulfonic acid in refluxing benzene is converted into 7-chloro-5-pyrrolidino-2,3-dihydro-1-benzothiepin-1,1-dioxide (IV). The condensation of (IV) with 3,4-dichlorophenyl isocyanate (V) in hot THF yields N-(3,4-dichlorophenyl)-7-chloro-5-pyrrolidino-2,3-dihydro-1-benzothiepin-4-carboxamide-1,1-dioxide (VI), which is finally hydrolyzed with HCl in refluxing ethanol - water.
