White solid | [Synthesis]
4-Trifluoromethylquinolin-2(1H)-one was prepared by reacting aniline and ethyl-4,4,4-trifluoroacetoacetate stirred in toluene. Experimental Procedure: In a 1 L round flask fitted with a reflux condenser a mixture of 25.60 g aniline, 50.0 g ethyl-4,4,4-trifluoroacetoacetate 300 ml toluene was heated to reflux in an oil bath at 130 °C. After
20 min 3 ml water was added and the mixture was heated at reflux for another 24 h. the reaction
mixture was cooled to room temperature and concentrated under reduced pressure. A round
flask with 200 mL H2SO4 was heated to 80°C and the crude oil from the step before was added
in portions to the H2SO4 keeping the internal temperature below 90°C, total addition time was
approximately 40 min. After addition was complete, the mixture was stirred at 80°C for 1 h,
cooled and poured onto 400 g crushed ice. The resulting solids were filtered, washed with water,
and dried under vacuum at 40°C to give 33.0 g (50%) product (4-Trifluoromethylquinolin-2(1H)-one) as a colorless solid. |
