Reaction Conditions

Reaction Steps

Under an atmosphere of nitrogen was added to a solution of 4-chloro-2-methylbenzaldehyde (10.0 g, 64.9 g) in acetic acid (70 mL) ammonium acetate (11.5 g, 149 mmol) and nitromethane (10.0 ml, 185 mmol). The solution was stirred at reflux (oil bath 140° C.) for 2 h. After cooling to ambient temperature water (70 mL) was added and extracted twice with ethyl acetate (70 mL). The organic layers were washed with water (70 mL) and brine (70 mL) and were dried over sodium sulfate. The filtrated was concentrated and the resulting solid was suspended in methanol (30 mL), at 0° C. filtered off and was washed with cold methanol (10 mL) affording the title compound (8.30 g, 65%) as a yellow solid. MS m/e: 197.0 [M]+.
