Procedure

(2R*,4S*)-4-{[3,5-Bis(trifluoromethyl)benzyl]-(5-carboxymethoxypyrimidin-2-yl)}amino-2-ethyl-6-methoxy-3,4-dihydro-2H-[1,5]naphthyridine-1-carboxylic acid ethyl ester (150 mg) is dissolved in N,N-dimethylformamide (1 ml), then thereto is added morpholine (30 μl). After addition of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide monohydrochloride (66 mg) and 1-hydroxybenzotriazole hydrate (46 mg) under ice-cooling, the mixture is stirred at room temperature for 4 hours. Water is added to the reaction mixture and the mixture is extracted with ethyl acetate. 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; chloroform:methanol=19:1) to give (2R*,4S*)-4-([3,5-bis(trifluoromethyl)benzyl]-{5-[2-(morpholin-4-yl)-2-oxoethoxy]pyrimidin-2-yl})amino-2-ethyl-6-methoxy-3,4-dihydro-2H-[1,5]naphthyridine-1-carboxylic acid ethyl ester (138 mg). MS (m/z): 727 [M+H]+
