A mixture of 4-(5-fluoro-pyridin-2-yloxymethyl)benzaldehyde (2.71 g, 11.7 mmol) described in Manufacturing Example 56-1-2, nitromethane (1.26 mL, 23.4 mmol), ammonium acetate (1.35 g, 17.6 mmol) and acetic acid (30 mL) was stirred for 10 hours at 100° C. This mixture was cooled to room temperature, concentrated under a reduced pressure, and diluted with ethyl acetate. The organic layer was washed with water, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated under a reduced pressure to obtain the title compound (2.9 g).
