Reaction Steps

4-Oxo-6-trifluormethoxy-2,3-dihydrofuro[3,2-c] quinoline (272 mg, 1.0 mmol) was dissolved in 10 ml of ethylene glycol in a pressure tube and 2-methoxyaniline (282 μl, 1.0 mmol) was added under nitrogen. The reaction mixture was heated at 210° C. for 15 hours. The reaction mixture was diluted with 20 ml of salt water and the aqueous layer was extracted with methylene chloride (15 ml×3). After washing with water (15 ml×3), the organic layer was dried by anhydrous magnesium sulfate and filtered, and concentrated under reduced pressure. The residue was purified with ethyl acetate as eluent by silica gel chromatography to obtain 286 mg of desired compound as solid in 76% of yield.
