Itaconic acid → 1-(4-Fluorophenyl)-5-oxopyrrolidine-3-carboxylic acid

Participants

Reaction Steps

4-Fluoroaniline (0.7 ml, 7.6 mmol) was added to 2-methylenebutanedioic acid (1.0 g, 7.6 mmol) in a sealed tube. The mixture was heated to 110 degrees for 3 hours after which a precipitate formed. The reaction was filtered and the solid was dissolved in ethyl acetate and concetrated to yield 1-(4-fluorophenyl)-5-oxopyrrolidine-3-carboxylic acid (M+1=223.8). The product was taken to next step without determining mass.
