A mixture of the 4-(4-fluoro-pyridine-2-yloxymethyl)-benzaldehyde (1.5 g, 6.49 mmol) described in Manufacturing Example 59-1-2, nitromethane (698 μL, 13 mmol), ammonium acetate (750 mg, 9.74 mmol) and acetic acid (15 mL) was stirred for 6 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 (1.72 g).
