Procedure
To a mixture of (5-chloropyridin-3-yl)methyl methanesulfonate (2.09 g, crude) in EtOH (45 mL) and water (5 mL) was added potassium cyanide (926 mg, 14.3 mmol), and the resulting mixture was stirred at 85° C. for 2 h. Sodium bicarbonate was added and the mixture was extracted with ethyl acetate, the organic layer was washed with brine, dried over anhydrous sodium sulfate and concentrated. The residue was purified by silica gel column chromatography (50% ethyl acetate in petroleum ether) to afford the title compound as a yellow solid (820 mg, 5.43 mmol, 48% yield, 2 steps). MS (ESI) m/z 153.1 [M+H]+.
