合成路线1
该中间体在本合成路线中的序号：(VII)4) The intermediate 4-(1-pyrrolidinylsulfonylmethyl)phenylhydrazine (III) can be obtained as follows: The condensation of pyrrolidine (VI) with 1-(4-nitrobenzylsulfonyl)chloride (VII) in dichloromethane gives the expected sulfonamide (VIII), which is reduced with H2 over RaNi in DMF, yielding 4-(1-pyrrolidinylsulfonylmethyl)aniline (IX). The diazotation of (IX) with NaNO2/HCl affords the corresponding diazo compound (X), which is finally reduced to the target intermediate (III) with SnCl2/HCl.
