Participants

Reaction Steps

4-Iodoaniline (25 g), ethyl acetoacetate (17.8 g) and polyphosphoric acid (112.5 g) in dioxane (500 mL) were refluxed for 20 hours. The reaction was diluted with water (2 L) and solid sodium carbonate added until the solution reached pH 10.0. The resulting precipitate was isolated by filtration, washed with water and dried under vacuum. Trituration with ether gave the sub-title compound (10 g) as a white solid.
