5-(4-Chlorobenzoyl)-4-(hydroxymethyl)-1-methyl-1H-pyrrole-2-acetic acid (2), the major oxidative metabolite of zomepirac (1), was synthesized starting with ethyl 5-(4-chlorobenzoyl)-1,4-dimethyl-1H-pyrrole-2-acetate (3), the ethyl ester of 1. Compound 3 was oxidized with selenium dioxide to afford the alpha-oxoester, 5. Bromination of 5 with N-bromosuccinimide produced bromomethylpyrrole 7, and reaction of 7
