A mixture of 4-(pyridin-2-yloxymethyl)-benzaldehyde described in Manufacturing Example 230-1-2 (26.8 g, 126 mmol), nitromethane (34 mL, 630 mmol), ammonium acetate (19 g, 252 mmol) and acetic acid (90 mL) was stirred for 1 hour and 30 minutes at 100° C. Ethyl acetate and water were added to the reaction solution, and liquid separation was carried out. This organic layer was separated, washed with water (5 times) and saturated aqueous sodium bicarbonate solution (once), dried over anhydrous magnesium sulfate, and then filtered. The filtrate was concentrated under a reduced pressure to obtain the title compound (31 g) as a crude product.
