Versuchsvorschrift
1-(2-Ethylphenyl)-4-oxo-6-trifluoromethoxy-2,3,4,5-tetrahydropyrrolo[3,2-c]quinoline(2.5 g, 6.7 mmol) was dissolved in phosphoryl chloride(10 ml), then the reaction mixture was refluxed for 2 hours. After removing the excess phosphoryl chloride by simple distillation, the residue was poured into iced water, neutralized with aqueous solution of sodium hydroxide(1N), stirred at room temperature for 30 minutes, and extracted with dichloromethane(20 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 to obtain 3.2 g of desired compound as solid in 85% of yield.
