실험 절차
Sodium cyanide (1.25 g, 25.4 mmol) was added to a solution of 5-(chloromethyl)-2-methoxypyridine (1.00 g, 6.34 mmol) in DMSO (10 ml) and stirred for 18 h at room temperature. After completion of reaction, the reaction mixture was diluted with brine and the compound was extracted with DCM (3×35 ml). The combined organic layers were dried over anhydrous sodium sulfate, filtered and evaporated. The crude compound was purified by column chromatography using 100-200 silica gel, 10% ethyl acetate in petroleum ether as eluent to afford 0.6 g (63.8%) of 2-(6-methoxypyridin-3-yl)acetonitrile as white color solid.
