Reaction Steps

Cyanoacetic acid (1.5 g; 17.6 mmol) and phosphorus pentachloride (4.1 g; 19.4 mmol) are heated under reflux in dichloromethane (40 ml) for 1 hour. 3-Methyl-4-nitroaniline (1.6 g; 10.6 mmol) is added and the mixture is heated for a further hour under reflux conditions. After cooling, the solid is filtered and stirred with water for a further hour, the mixture is filtered and the filtrate is brought to dryness under reduced pressure. 2-Cyano-N-(3-methyl-4-nitrophenyl)acetamide (1.4 g; 64%) is thus obtained.
