実験手順
To a mixture of 100 mg of tert-butyl[(1R)-1-(1-naphthyl)ethyl][(3-phenylpiperidin-4-yl)methyl]carbamate, 59.4 mg of ethyl 5,6-dichloronicotinate, and 37.3 mg of potassium carbonate was added 2.0 mL of DMSO at room temperature, and the mixed solution was stirred at 100° C. overnight. After cooling to room temperature, water was added thereto. After extraction with ethyl acetate, the organic layer was dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane-ethyl acetate) to obtain 128 mg of ethyl 6-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-phenylpiperidin-1-yl]-5-chloronicotinate as a colorless foamy substance. FAB+: 628
