Versuchsvorschrift

A suspension of 4-chloro-8-nitroquinoline (200 mg, 0.96 mmol), 3-(trifluoromethyl)phenol (250 mg, 1.54 mmol), K2CO3 (414 mg, 2.99 mmol) in CH3CN (2 mL) was heated in a sealed tube at 100° C. for 8 h. Then the reaction mixture was quenched with water and was extracted with EtOAc. The organic layer was washed with brine, separated, dried, filtered and concentrated. The residue was purified by column chromatography to afford 120 mg of the title product. 1H NMR (300 MHz, DMSO d6): δ 8.83 (d, J=5.4 Hz, 1H), 8.60-8.57 (d, J=8.4 Hz, 1H), 8.36 (d, J=6.9 Hz, 1H), 7.85-7.73 (m, 5H), 6.87 (d, J=5.4 Hz, 1H).
