Reaction Conditions

Reaction Steps

To a solution of 6-bromopyridin-3-ol (10 g, 57.80 mmol) in DMF (60 mL) was added 4-fluorobenzonitrile (6.99 g, 57.8 mmol) and K2CO3 (11.9 g, 86.70 mmol) and the reaction mixture was stirred at 80° C. for 16 hours (h). The reaction mixture was poured into ice water and extracted with ethyl acetate. The organic layer was dried over sodium sulphate and concentrated. The crude product was purified by column chromatography (silica gel, 100-200 mesh) to obtain the title compound as an off-white solid (10 g, 63%): mp 113° C.; 1H NMR (400 MHz, CDCl3) δ 8.22 (d, J=2.9 Hz, 1H), 7.70-7.63 (m, 2H), 7.56-7.51 (m, 1H), 7.28 (dd, J=8.5, 2.9 Hz, 1H), 7.10-7.02 (m, 2H); EIMS m/z 275.
