Reaction Steps

A mixture of 4-acetamido-3-methylbenzaldehyde (1.23 g), malonic acid (795 mg), pyridine (549 mg) and ethanol (1.7 ml) was refluxed for 3 hours under nitrogen atmosphere. To the mixture was added ethanol (1.7 ml), and the mixture was stirred for 30 minutes under ice-bath cooling. The resulting precipitate was collected by filtration and washed with ethanol to give 4-acetamido-3-methylcinnamic acid (1.08 g).
