실험 절차
To a solution of 5-(hydroxymethyl)picolinonitrile (1.59 g, 11.9 mmol) in 80 mL of DCM was added diisopropylethylamine (3.2 mL), followed by a solution of methanesulfonyl chloride (1.49 g, 13.0 mmol) in 20 mL of DCM at 0° C. The solution was stirred at 0° C. for 40 min and washed with 5% citric acid, sat. NaHCO3 (aq.) and brine. After concentration, the residue was purified by silica gel chromatography (elution with 0-30% EtOAc/Hex) to afford (6-cyanopyridin-3-yl)methyl methanesulfonate (2.33 g).
