Versuchsvorschrift

To a mixture of 4-(2-fluoro-4-nitrophenoxy)quinolin-7-ol (5 g, 16.7 mmol) and NaOH (6.7 g, 166.7 mmol) in acetone (67 mL) was added chloroform (21.9 g, 183.3 mmol) dropwise at room temperature. After the mixture turned brown color, the reaction was heated to reflux for 1 hour. Water (10 mL) was then added to the reaction mixture, and the resulted solution was adjusted to pH 3˜4 with 1 N HCl solution. The resulted mixture was concentrated in vacuo, and then extracted with EtOAc (30 mL). The organic phase was separated, concentrated in vacuo, and treated with 95% EtOH (10 mL). The resulted solid was collected by filtration, dried in vacuo overnight to afford the title compound as a brown solid (2.34 g, 36.4%).
