1-(2-Methyl-4-benzyloxyphenyl)-4-chloro-6-β,β,β-trifluoroethoxy-2,3-dihydropyrrolo[3,2-c]quinoline(749 mg, 1.5 mmol) was dissolved in ethanolamine(10 ml), and the resultant was refluxed at 180° C. for 15 hours. The reaction mixture was dissolved in water, extracted with dichloromethane, and the organic layer was washed with water for 3 times. The organic layer was dried over anhydrous magnesium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography(ethyl acetate) to obtain 650 mg of desired compound as solid in 83% of yield.
