実験手順

To a solution of 4-chloro-N-[(3R,4R)-3-(3,4-dichlorophenyl)piperidin-4-yl]-N-methylbenzamide monohydrochloride (200 mg) obtained in Example 137a, 1-acetylpiperidine-4-carboxylic acid (118 mg) and triethylamine (127 μL) in acetonitrile (5 mL) were added WSC.HCl (176 mg) and HOBt (140 mg), and the mixture was stirred at room temperature for 14 hr. The reaction mixture was poured into water, and the resultant product was extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium hydrogen carbonate solution and brine and dried, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (NH Chromatorex) (solvent gradient; 15→100% ethyl acetate/hexane) to give the title compound (113 mg, 44%) as a white powder.
