Procedure

To a mixture of 136 mg of the crude tert-butyl[(1R)-1-(1-naphthyl)ethyl][(3-phenylpiperidin-4-yl)methyl]carbamate, 64 mg of methyl 2-bromo-1,3-thiazole-4-carboxylate, and 38 mg of potassium carbonate was added 1.5 mL of DMSO at room temperature, and the mixed solution was stirred at room temperature overnight. To the reaction mixture was added water, followed by extraction with ethyl acetate, and the organic layer was then washed with water and saturated brine in this order, and then 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 113 mg of methyl 2-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-phenylpiperidin-1-yl]-1,3-thiazole-4-carboxylate as a colorless foamy substance. ESI+: 586
