合成路线1
该中间体在本合成路线中的序号：(XVII)The methylation of 2-hydroxy-4-(4-methylphenylsulfonamido)benzoic acid (XVI) with dimethyl sulfate and KOH in refluxing acetone gives the N,O-dimethylated benzoic acid (XVII), which is chlorinated by means of NCS in hot DMF to yield the chlorobenzoic acid derivative (XVIII). The hydrolysis of (XVIII) with H2SO4 affords 5-chloro-3-methoxy-4-(methylamino)benzoic acid (XIX), which is finally condensed with the aminodiazepine (XV) by means of EDC in dichloromethane to obtain the target chiral benzamide derivative.
