실험 절차

To a dichloromethane (5.00 mL) solution of (6-phenoxy-pyridin-3-yl)-methanol (458 mg, 2.28 mmol) described in Manufacturing Example 193-1-1 was added dropwise thionyl chloride (333 μL, 4.56 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 at room temperature, 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 (450 mg, 89.8%).
