A new and one-pot synthesis of benzofuran fused N-heterocycles has been accomplished via AlCl3-mediated C–C followed by C–Obondformationbetween 2,3-dichloropyrazine or its derivatives and phenols. The methodology provided novel compounds as potential inhibitors of PDE4B. The single crystal X-ray data of a synthesized benzofuran derivative are presented. Scope of the methodology, in vitro pharmacological
