A Convenient Synthesis of Pyrazole‐imidazoline Derivatives by Microwave Irradiation

摘要

> A series of 28 hybrids pyrazole‐imidazolines 1a – n and 2a – n were synthesized by a new methodology using microwave irradiation, in short time (20–30?min), in low power (50–70?W), and in 34–92% yield. Among all methodologies evaluated, no side products were obtained. All derivatives were completely characterized by FT–IR, 1 H and 13 C NMR, GC–MS, and HRMS.
