実験手順

A mixture of (2R,4S)-4-{[3,5-Bis(trifluoromethyl)benzyl]-[5-(morpholin-4-yl)pyrimidin-2-yl]}amino-2-ethyl-6-trifluoromethanesulfonyloxy-3,4-dihydro-2H-[1,5]naphthyridine-1-carboxylic acid ethyl ester (732 mg), tetrakis(triphenylphosphine)palladium (catalytic amount), zinc cyanide (142 mg) and N,N-dimethylformamide (10 ml) is stirred at 95° C. under nitrogen flow for 8 hours. After cooling to room temperature, water and ethyl acetate are added to the reaction solution. The organic layer is washed with a saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure. The resulting residue is purified by column chromatography (silica gel; hexane: ethyl acetate=4:1→2:1) to give (2R,4S)-4-{[3,5-bis(trifluoromethyl)benzyl]-[5-(morpholin-4-yl)pyrimidin-2-yl]}amino-6-cyano-2-ethyl-3,4-dihydro-2H-[1,5]naphthyridine-1-carboxylic acid ethyl ester (572 mg). MS (m/z): 664 [M+H]+
