In 77 ml of CHCl3 was dissolved 7.00 g (0.0511 mole) of (2,6-dimethyl-4-pyridyl)methanol and with stirring at room temperature, 15.3 ml of thionyl chloride was added dropwise. After completion of the dropwise addition, the mixture was stirred for 3 hours and concentrated. The residue was diluted with aqueous sodium hydrogen carbonate solution and extracted with AcOEt (100 ml×3). The extract was dried over MgSO4 and distilled to remove AcOEt. The procedure gave 6.37 g of (2,6-dimethyl-4-pyridyl)methyl chloride as oil.
