Abstract
Paal–Knorr condensation of 2,5‐hexadione with primary amines in the presence of a catalytic amount of sulfamic acid under solvent‐free conditions has been accomplished with an excellent yield. This is a very easy, rapid, and high‐yielding reaction for the synthesis N‐substituted pyrrole derivatives.
