(2-Methyl-pyridin-4-yl)-methanol (40 mg, 0.33 mmol) described in Manufacturing Example 47-1-1, thionyl chloride (0.047 ml, 0.65 mmol) and methylene chloride (4.0 ml) were stirred for 5 minutes at 60° C. Sodium bicarbonate solution and ethyl acetate were added to separate the reaction solution, and the ethyl acetate layer was dried over sodium sulfate. The solvent was evaporated under a reduced pressure to obtain 4-chloromethyl-2-methyl-pyridine as a crude product.
