실험 절차
3-Bromobenzaldehyde (10.0 g, 54 mmol), malonic acid (10.1 g, 97 mmol) and piperidine (0.267 mL, 2.7 mmol) are treated with pyridine (30 mL) and heated at 100° C. for 3.5 h. The reaction mixture is cooled to room temperature, poured into 200 ml of 20% hydrochloric acid at 0° C.; the resultant precipitate is collected, washed with copious amounts of water and dried in a vacuum dessicator overnight to afford the title compound (11.64 g, 51 mmol).
