反应详情

The above pyridine (5.13 g, 20.4 mmol) was stirred in 50.1 mL of a 5.6:1 solution of ethanol:deionized water. To this mixture was added sodium cyanide (1.20 g, 24.5 mmol), which was stirred for 2 hours and 30 minutes. The reaction mixture was diluted with dichloromethane (100 mL), washed with water (3×100 mL), and partitioned between water and dichloromethane. The organic layer was dried over sodium sulfate, filtered, concentrated, and subjected to silica gel chromatography eluting with 5-30% EtOAc in hexanes to yield (3-bromopyridin-2-yl)acetonitrile.
