반응 단계
A mixture of 3-(pyridin-2-ylmethoxy)-benzaldehyde (2.98 g, 14 mmol) described in Manufacturing Example 60-1-1, nitromethane (1.51 mL, 28 mmol), ammonium acetate (1.62 g, 21 mmol) and acetic acid (30 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, and the residue was purified by silica gel column chromatography (heptane:ethyl acetate=4:1-2:1-1:1) to obtain the title compound (2.56 g, 71%).
