To a suspension of 6-bromo-1,2,3,4-tetrahydronaphthalen-1-one (2.0 g, 8.9 mmol), 4-fluoro-2-methylphenol (1.7 g, 13.3 mmol), 1-pyridin-2-ylacetone (240 mg, 1.8 mmol) and Cs2CO3 (5.8 g, 17.8 mmol) in DMSO (40 mL) was added CuBr (127 mg, 0.9 mmol) at rt under N2. The reaction was stirred at 100° C. overnight. The reaction was cooled, diluted with water (50 mL), and extracted with EtOAc (3×50 mL). Organics were washed with water (3×50 mL) and brine (50 mL), dried (Na2SO4), and concentrated. Purification by silica gel chromatography (PE:EtOAc=30:1) gave 2.3 g (95%) of the title compound as a colorless oil. [M+H] Calc'd for C17H15FO2, 271. Found, 271.
