Reaction Steps
4-[(3-Methyl-4-oxo-1,4-dihydroquinolin-2-yl)methoxy]-2-(tetrahydro-2H-pyran-4-ylmethoxy)benzoic acid (67 mg) and 1-hydroxybenzotriazole hydrate (25 mg) were dissolved in DMF (1.3 mL). To this solution were sequentially added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (33 mg) and morpholine (15 mg), and the mixture was stirred at room temperature for 12 hours. A saturated aqueous sodium hydrogen carbonate solution (5 mL) to the reaction mixture, followed by extraction with ethyl acetate (50 mL). The organic layer was washed sequentially with water and saturated brine, and then dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (eluent: chloroform/methanol=15/1) to obtain 3-methyl-2-{[4-(morpholin-4-ylcarbonyl)-3-(tetrahydro-2H-pyran-4-ylmethoxy)phenoxy]methyl}quinolin-4(1H)-one (73 mg).
