Reaction Steps

(2R,4S)-4-{[3,5-Bis(trifluoromethyl)benzyl]-[5-(2-carboxyvinyl)pyrimidin-2-yl]}amino-2-ethyl-6-methoxy-3,4-dihydro-2H-[1,5]naphthyridine-1-carboxylic acid ethyl ester (500 mg) is dissolved in a mixed solution of tetrahydrofuran (15 ml) and methanol (5 ml), then thereto is added 10% palladium/carbon (160 mg), and the mixture is stirred at room temperature under hydrogen for 3 hours and 30 minutes. The reaction solution is filtered, and concentrated under reduced pressure to give (2R,4S)-4-{[3,5-bis(trifluoromethyl)benzyl]-[5-(2-carboxyethyl)-pyrimidin-2-yl]}amino-2-ethyl-6-methoxy-3,4-dihydro-2H-[1,5]naphthyridine-1-carboxylic acid ethyl ester (498 mg). MS (m/z): 656 [M+H]+
