1-Benzyl-5-ethyl-5-hy­droxy-1H-pyrrol-2(5H)-one

The title compound, C₁₃H₁₅NO₂, was obtained as a by-product in the Grignard reaction of malimide. The dihedral angle between the five-memebred ring (r.m.s. deviation = 0.005 Å) and the benzene ring is 67.20 (14)°. The benzene ring and the ethyl chain lie to the same side of the five-membered ring. In the crystal, mol­ecules are linked by O—H...O hydrogen bonds, generating C(6) chains propagating in [010].
