Procedure
To a stirred solution of ethyl N-[4-(2-bromoethyl)-3-chlorophenyl]aminoacetate (79 mg) in dichloromethane (2 ml) was added tert-butyl hypochlorite (31 μl) under ice-cooling, and the mixture was stirred for 6 hours at room temperature. The solvent was removed in vacuo, and purification of the residue by flash column chromatography on silica gel (eluent: hexane/ethyl acetate=15/1) gave ethyl N-[4-(2-bromoethyl) -2,3-dichlorophenyl]aminoacetate (31 mg) as a high-polar regioisomer and ethyl N-[4-(2-bromoethyl)-2,5-dichlorophenyl]aminoacetate (34 mg) as a low-polar regioisomer.
