Reaction Steps

3-phenoxy-8-(trifluoromethyl)quinolin-4-ol: A solution of 3-bromo-8-(trifluoromethyl)quinolin-4-ol (1.28 g, 4.38 mmol), potassium phenoxide (4.24 g, 45.1 mmol), and copper powder (0.100 g, 1.61 mmol) in DMF (30 mL) is treated with CuBr (0.943 g, 6.57 mmol) and heated at reflux for 6 days. The cooled reaction is poured into 2N aq HCl and extracted with ethyl acetate. The combined extracts are washed with sat aq NaHCO3, water, brine, and dried with magnesium sulfate. The extracts are concentrated and the residue is chromatographed with 1:9 ethyl acetate:hexanes to afford the title compound as a orange solid (0.471, 35%). mp 153-155° C.; Calcd mass for C16H10NF3O2 is 305.25, found by ESI MS, 306 (M+H)+.
