Reaction Steps
A mixture of 4-bromobenzaldehyde (16.8 g, 91 mmol), nitromethane (24.6 mL, 455 mmol), ammonium acetate (14 g, 182 mmol), and acetic acid (160 mL) was stirred for 4 hours at 100° C. This mixture was cooled to room temperature and poured into water. The precipitate thus produced was collected, washed with water, and dried under a reduced pressure to obtain the title compound (17.4 g). The title compound was used in the following reaction without any further purification.
