실험 절차

To a mixture of dichloromethane (5 mL) and the (6-methoxy-pyridin-2-yl)-methanol (105 mg, 0.75 mmol) described in Manufacturing Example 99-1-1 was added thionyl chloride (82.4 μL, 1.13 mmol), which was stirred for 30 minutes at room temperature. A saturated sodium hydrogencarbonate aqueous solution was added to this reaction mixture, which was then extracted with dichloromethane. The organic layer was separated, washed with water and saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated under a reduced pressure to obtain the title compound (105.8 mg, 89%).
