実験手順
A 0.3 ml portion of oxalyl chloride and one drop of DMF were added to a 20 ml THF solution containing 1.00 g of 3-[4-(3-chlorophenyl)-l-ethyl-7-methyl-2-oxo-1,2-dihydro-1,8-naphthyridin-3-yl]propanoic acid, followed by stirring at room temperature for further 30 minutes. The reaction mixture was added dropwise to an ice-cooled 10 ml THF solution containing 1.0 ml of morpholine, followed by stirring for 30 minutes. To the reaction mixture was added 1M hydrochloric acid and the whole was extracted with ethyl acetate. The organic layer was washed with water and saturated brine and then the solvent was evaporated. The resulting residue was purified by a silica gel column chromatography (chloroform-methanol) and then recrystallized from diisopropyl ether-ethyl acetate to obtain 780 mg of 4-(3-chlorophenyl)-1-ethyl-7-methyl-3-[3-(morpholin-4-yl)-3-oxopropyl]-1,8-naphthyridin-2(1H)-one as colorless crystals.
