Procedure

A solution of 1-(5-fluoropyrimidin-2-yl)ethanone (700 mg, 5.0 mmol) and 4-fluorophenol (616 mg, 5.50 mmol) in 6 mL DMF was treated with potassium carbonate (829 mg 6.0 mmol) and heated to 50° C. for 3.5 h. The reaction mixture was poured into 20 mL water, and extracted with EtOAc (2×20 mL). Organics were washed with 20 mL each water, brine, and dried over Na2SO4. Mixture was filtered and concentrated on silica gel. Column chromatography (10-100% EtOAc/hept) gave 295 mg (25%) 1-(5-(4-fluorophenoxyl)pyrimidin-2-yl)ethanone as a white solid used directly in the following step. MS m/z 233.2 (M+H)+. 1H NMR (400 MHz, CDCl3) δ 8.55 (s, 2H), 7.23-7.07 (m, 4H), 2.78 (s, 3H).
