実験手順
4-Oxo-6-trifluoromethoxy-2,3,4,5-tetrahydrofuro[3,2-c]quinoline(5.0 g, 19 mmol) was dissolved in diethylene glycol(30 ml) and 2-methyl-4-methoxyaniline(6.1 ml, 46 mmol) was added. The reaction mixture was refluxed at 250° C. for 15 hours, diluted in brine(20 ml), and the aqueous layer was extracted with dichloromethane(15 ml) for 3 times. The organic layer was washed with water(15 ml) for 3 times, dried over anhydrous magnesium sulfate, filtered, and concentrated under reduced pressure. The residue was purified with ethyl acetate as eluent by silica gel chromatography to obtain 6.6 g of desired compound as solid in 91% of yield.
