Trifluoroacetic acid → (3-Benzyl-2-oxoimidazolidin-1-yl)acetic acid

Participants

Reaction Steps

To a solution of tert-butyl 2-(2-oxo-3-benzylimidazolidinyl)acetate (2.51 g, 8.64 mmol) in dichloromethane (15 ml) was added trifluoroacetic acid (10 ml). After stirring the mixture at room temperature for 1 hour, the solvent was removed under reduced pressure. The oily residue was crystallized by treating with ethyl acetate and filtered off to give 2-(2-oxo-3-benzylimidazolidinyl)acetic acid (1.56 g).
