Synthesis of N-(o-amino aryl) pyrroles by Paal-Knorr reaction

N-(o-nitro aryl)- and N-(o-acetamino aryl)-2, 5-dimethyl pyrroles are synthesized by Paal-Knorr reaction by condensing acetonyl acetone with o-nitro anilines and o-acetamino anilines respectively. Reduction of the nitro aryl pyrroles and hydrolysis of acetamino aryl pyrroles yielded the corresponding N-(o-amino aryl)-2, 5-dimethyl pyrroles
