Reaction Steps

The crude 3-carboethoxy-2-methylpyr-4-one isolated from the previous reaction is dissolved in 50 ml toluene. 2.4 g of aniline and 400 mg of p-toluenesulfonic acid monohydrate are added and the mixture refluxed for 1 hour. Evaporation of the solvent leaves 6.3 g of crude 3-carboethoxy-N-phenyl-2-methylpyrid-4-one.
