5-(Arylcyanohydroxymethyl)-1-loweralkylpyrrole-2-acetic acid derivatives are prepared by the protic acid catalyzed reaction of aroylcyanides with 1-loweralkylpyrrole-2-acetic acid derivatives, which is then converted by treatment with alkali metal hydroxides or heat to form 5-aroyl-1-loweralkylpyrrole-2-acetic acid or derivatives thereof.
