To a solution of 158 mg of (1R)-1-(1-naphthyl)-N-[(4-phenylpiperidin-3-yl)methyl]ethaneamine and 0.100 mL of triethylamine in 3.0 mL of toluene was added 83 mg of methyl 2-isocyanatobenzoate at room temperature. It was stirred at 90° C. overnight, and then cooled to room temperature. The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (chloroform-methanol) to obtain 27.3 mg of methyl 2-({[3-({[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-4-phenylpiperidin-1-yl]carbonyl}amino)benzoate as a colorless foamy substance.
