beige crystalline powder | [General Description]
4-Chloro-2,8-bis(trifluoromethyl)quinolone is the intermediate formed during the synthesis of quinoline derivatives. | [Synthesis]
General procedure for the synthesis of 4-chloro-2,8-bis(trifluoromethyl)quinoline from 2,8-bis(trifluoromethyl)-4-hydroxyquinoline: 2,8-bis(trifluoromethyl)quinolin-4-ol (0.25 g, 0.89 mmol) was dissolved in phosphorus trichloride (5 mL) and the reaction was carried out at reflux for 5 h at 80 °C under nitrogen protection. Upon completion of the reaction, the reaction mixture was quenched with 30 mL of ice water and extracted with dichloromethane (2 x 20 mL). The organic phases were combined, dried with anhydrous magnesium sulfate, filtered and concentrated under reduced pressure to give a light yellow solid product (0.13 g, 50% yield), which could be used in subsequent reactions without further purification. | [References]
