We studied the reactions of some N ‐methylpyrrole derivatives with isopropenyl acetate and different acetic anhydrides. We have found that the reaction with isopropenyl acetate afforded 5‐acetylpyrrole derivatives while with acetic anhydrides acetylation occurred on the α‐carbon atom of the side‐chain of pyrrole‐2‐acetic acid derivatives.
