反応手順

To a solution of 217 mg of the crude product of (1R)-1-(1-naphthyl)-N-[(4-phenylpiperidin-3-yl)methyl]ethaneamine and 0.175 mL of triethylamine in 4.0 mL of THF was added 243 mg of methyl 3-chloro-4-{[(4-nitrophenoxy)carbonyl]amino}benzoate. After stirring at room temperature overnight, the reaction mixture was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane-ethyl acetate) to obtain 214 mg of methyl 3-chloro-4-({[3-({[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-4-phenylpiperidin-1-yl]carbonyl}amino)benzoate.
