Etherification of 2-acetoxymethylpyrrole derivative with sodium alkoxide at reflux was investigated in details resulting in the smooth formation of the corresponding 2-alkoxymethylpyrrole derivative in excellent yield. A plausible mechanism involving the formation of a highly reactive intermediate azafulvene species was proposed to explain the observed transformation. An alternate method for the preparation of 2-alkoxymethylpyrrole derivative starting from 2-acetoxymethylpyrrole derivative in alkaline media was provided.

Key words: 2-acetoxymethylpyrrole derivative, 2-alkoxymethylpyrrole derivative, etherification, azafulvene, sodium alkoxide
