To a dichloromethane (4.00 mL) solution of (6-benzyloxy-pyridin-3-yl)-methanol (1.80 g, 8.36 mmol) described in Manufacturing Example 191-1-1 was added dropwise thionyl chloride (732 μL, 10.0 mmol) on an ice bath (0° C.) under nitrogen atmosphere, which was stirred for 5 minutes at room temperature. Aqueous sodium bicarbonate was added to the reaction solution, which was extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium chloride and dried over anhydrous magnesium sulfate, and the solvent was evaporated under a reduced pressure to obtain the title compound (1.70 g, 87.0%).
