| Abstract: | An efficient method to prepare 2,3-diarylimidazo1,2-a]pyridines is described. The procedure involves a Suzuki cross-coupling reaction followed by a direct arylation at position 3. Imidazo1,2-a]pyridin-2-yl triflate was identified as a suitable coupling partner, permitting access to a variety of highly functionalized 2,3-diarylimidazo1,2-a]pyridines. |
