To a mixture of 5-fluoropyridin-3-ol (0.95 g, 8.40 mmol) and K2CO3 (1.16 g, 8.40 mmol) in CH3CN (6 mL) was added dropwise 2-bromoacetonitrile (1.01 g, 8.42 mmol) at rt and upon the end of addition the mixture was stirred at rt for 40 h. The mixture was filtered and the filtrate was concentrated in vacuo. The residue was purified by a silica gel column chromatography (PE/EtOAc (V/V)=3:1) to give the title compound as a yellow solid (0.55 g, 43%).
