A suitable and efficient method for the synthesis of N ‐aryl pyrroles by using 2,5‐dimethoxy tetrahydrofuran and several primary aromatic amines in the presence of the catalytic amount of [H‐NMP][HSO 4 ] under room temperature was described. This method has the advantages such as; easy reaction workup, absolutely separated of catalyst from the reaction mixture and smoothly recyclability of catalyst. In this reaction, N ‐substituted pyrroles were obtained as desired products in excellent yields and short reaction times via green and one‐pot procedure.
