Reaction Steps

1-(2-Ethylphenyl)-4-chloro-6-trifluoromethoxy-2,3-dihydropyrrolo[3,2-c]quinoline(801 mg, 2.0 mmol) was dissolved in ethanolamine(10 ml), and the reaction mixture was refluxed at 190° C. for 3 hours. The excess solvent was removed by distillation under reduced pressure, and the residue was diluted in dichloromethane(20 ml), then washed with water(15 ml) 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 chromatography to obtain 530 mg of desired compound as solid in 62% of yield.
