実験手順

A mixture of 100 mg of tert-butyl[(1R)-1-(1-naphthyl)ethyl][(3-phenylpiperidin-4-yl)methyl]carbamate, 56 mg of methyl 2,6-dichloroisonicotinate, 95 mg of potassium phosphate, 6 mg of bis(tri-tert-butylphosphine)palladium(0), and 2.0 mL of dimethylacetamide was stirred at 100° C. overnight. The reaction mixture was cooled to room temperature, and water was added thereto, followed by extraction with ethyl acetate. The organic layer was washed with saturated brine, and dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane-ethyl acetate) to obtain 66 mg of methyl 2-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-phenylpiperidin-1-yl]-6-chloroisonicotinate as a pale yellow oily compound. ESI+: 614
