Reaction Steps
In a round-bottomed flask equipped with a Dean-Stark apparatus, 10 g of resorcinol and 11.8 g of itaconic acid were dissolved in 150 ml of a toluene/dioxane mixture (volume ratio 1/1) in the presence of Amberlyst 15 resin from Aldrich. The reaction mixture was heated at 100° C. for 3 hours. After cooling, the crude reaction product was filtered and the filtrate was concentrated under vacuum. The crude product was recrystallized hot from ethyl acetate. This gave 10 g of a white powder, which corresponds to the expected product (50% yield).
