Reaction Steps

A mixture of 4-(pyridin-2-yloxy)-benzaldehyde (9.3 g, 47 mmol) described in Manufacturing Example 209-1-1, nitromethane (14 g, 230 mmol), ammonium acetate (11 g, 140 mmol), and acetic acid (50 mL) was stirred for 1 hour and 30 minutes at 100° C. This mixture was cooled to room temperature, and water was added to precipitate a solid. The solid was filtered to obtain the title compound (9.9 g, 87%).
