Reaction Steps

4-Oxo-6-trifluoromethoxy-2,3,4,5-tetrahydrofuro[3,2-c]quinoline(272 mg, 1.0 mmol) was dissolved in diethylene glycol(10 ml), and 2-methoxyaniline(281 μl, 2.5 mmol) was added under nitrogen. The reaction mixture was refluxed at 250° C. for 15 hours. The reaction mixture was 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 by silica gel chromatography with ethyl acetate as eleunt to obtain 298 mg of desired compound as solid in 76% of yield.
