Participants

Reaction Steps

To N-[2-(3,4-dichlorophenyl)-4-(4-hexylaminopiperidino)butyl]-N-methylbenzamide in dichloromethane (5 mL) was added triethylamine (0.39 mL) and acetic anhydride (0.39 mL). After being stirred for 2 hours, the mixture was diluted with 1N sodium hydroxide and was extracted with dichloromethane. The combined organic extracts were washed (brine), dried, and evaporated. The resulting material was chromatographed, with dichloromethane:methanol (97:3) as the eluent, to give the title compound (0.210 g) as a white solid after evaporation from methanolic hydrogen chloridel MS: m/z=560(M+1). Analysis for C31H43Cl2N3O2.1.5 HCl: Calculated: C, 60.51; H, 7.28; N, 6.82; Found: C, 60.50; H, 7.38; N, 6.85.
