Procedure

Benzoyl chloride (0.21 ml) was added to a solution of N-[1-(3-amino-4-chlorophenyl)-1-methylethyl]-3-(imidazol-1-yl)propylamine (0.50 g) in dichloromethane (50 ml) and triethylamine (0.25 ml) with stirring at 0° C. The mixture was allowed to warm up to ambient temperature and stirred at this temperature for 18 hours. The mixture was washed with water, dried and evaporated. The residue was purified by flash column chromatography on silica using ethyl acetate/methanol/triethylamine (8:1:1) as the mobile phase. The product was obtained as an oil which was added to ethereal hydrogen chloride to produce a gum. The gum was triturated and then left standing for 18 hours. The resulting solid was ground up, filtered and dried to give 2'-chloro-5'-{1-[3-(imidazol-1-yl)propylamino]-1-methylethyl}benzanilide.
