Procedure
(2R,4S)-4-{(3-Cyano-5-trifluoromethylbenzyl)-[5-(morpholin-4-yl)pyrimidin-2-yl]}amino-2-ethyl-6-methoxy-3,4-dihydro-2H-[1,5]naphthyridine-1-carboxylic acid ethyl ester (315 mg) is dissolved in methanol (9 ml), and thereto is added 1N aqueous NaOH solution (1 ml). The mixture is stirred at room temperature for 1 day, and partitioned by adding 1N HCl and ethyl acetate. The organic layer is washed with saturated brine and dried over magnesium sulfate, then concentrated under reduced pressure. The resulting residue is purified by column chromatography (silica gel; hexane:ethyl acetate=7:3→3:7→0:1) to give (2R,4S)-2-ethyl-6-methoxy-4-{(3-methoxycarbonyl-5-trifluoromethylbenzyl)-[5-(morpholin-4-yl)pyrimidin-2-yl]}amino-3,4-dihydro-2H-[1,5]naphthyridine-1-carboxylic acid ethyl ester (54 mg). MS (m/z): 659 [M+H]+.
