摘要
A feasible approach to synthesize 1,5-diaryl-4-pyridyl-1,2,3-triaozle via a sequential route from 2-alkynyl pyridine was developed. In this work, KOH was identified as a crucial base to promote the Pd-catalyzed arylation step. Compared to the reported methods, this protocol largely improved the reaction efficiency with overall excellent yield and good functional group tolerance.
