Participants

Reaction Steps

To a solution of N-[(3R,4R)-3-(3,4-dichlorophenyl)piperidin-4-yl]-N-methyl-4-morpholin-4-ylbenzamide monohydrochloride (800 mg) obtained in Example 614, step 3, 1-(tert-butoxycarbonyl)piperidine-4-carboxylic acid (566 mg) and triethylamine (684 μL) in acetonitrile (5 mL) were added WSC.HCl (473 mg) and HOBt (378 mg), and the mixture was stirred at room temperature for 14 hr. To the reaction solution was added 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 to give the title compound (855 mg, 79%) as a white powder.
