(2) Synthesis of 2,4-dichloro-3-nitroquinoline: In a 20 mL round-bottomed flask, 3-nitroquinoline-2,4-diol (1 g, 4.85 mmol), phosphorus trichloride (appropriate amount) and N,N-dimethylaniline (0.19 mL) were added sequentially. The reaction mixture was stirred at 90 °C for 2 hours. Upon completion of the reaction, the reaction solution was cooled to room temperature, slowly poured into ice water, and stirring was continued for 0.5 hours. The precipitate precipitated was collected by filtration and dried under vacuum overnight. The crude product was purified by silica gel column chromatography (eluent: petroleum ether/ethyl acetate=5:1, v/v) to give 0.7 g of white solid product in 59.4% yield. | [References]
