実験手順

To an acetic acid (17.0 mL) solution of 4-(pyridine-3-yloxy)-benzaldehyde (1.70 g, 8.53 mmol) described in Manufacturing Example 76-1-1 were added nitromethane (2.60 g, 42.7 mmol) and ammonium acetate (1.32 g, 17.1 mmol) under nitrogen atmosphere, which was stirred for 3 hours at 110° C. Water and ethyl acetate were added to the reaction solution, and the organic layer was then extracted with ethyl acetate. The organic layer was 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 (2.00 g) as a crude product.
