実験手順

N-[2-(3,4-Dichlorophenyl)-4-oxobutyl]-N-methylbenzamide (870 mg) in methanol (2.4 mL) was added to a solution of 4-(2-oxopyrrolidin-1-yl)piperidine (0.460 g) and acetic acid (0.16 mL) in methanol (2.4 mL). After 5 minutes, sodium cyanoborohydride (0.173 g) in methanol (2.4 mL) was added in a single portion. After being stirred for 3 hours, the reaction mixture was diluted with aqueous sodium bicarbonate, stirred for 30 minutes, and extracted with dichloromethane. The organic extracts were dried, evaporated, and chromatographed, with dichloromethane:methanol (gradient 98:2, 90:10) as the eluent. The resulting material was dissolved in dichloromethane, precipitated out as the hydrochloride salt with ethereal hydrogen chloride, evaporated, and placed under high vacuum overnight to give the title compound (1.0 g) as a white solid; MS: m/z=502(M+1). Analysis for C27H33Cl2N3O2.1.50 HCl: Calculated: C, 58.20; H, 6.24; N, 7.54; Found: C, 58.18; H, 6.27; N, 7.44.
