A facile synthesis of methyl 1,5-diaryl-1H-pyrrole-2-carboxylates was reported in this article. Acid-catalyzed reaction of methyl 2-aroyl-1-phenoxycyclopropanecarboxylates with aromatic amines underwent smoothly to give methyl 1,5-diaryl-1H-pyrrole-2-carboxylates in high to excellent yields under mild conditions.
