Procedure
In 100 ml of cold water was dissolved 8.98 g of sodium borohydride and with ice-cooling and stirring, 11.7 g (0.0665 mole) of 2-chloronicotinyl chloride was added in small portions. The mixture was further stirred at the same temperature for 30 minutes and, then, extracted with Et2O (100 ml×3). The extract was dried over MgSO4 and distilled to remove Et2O. The procedure gave 8.75 g of (2-chloro-3-pyridyl)methanol as a pale yellow oil. When left standing at room temperature, this product solidified thoroughly.
