Convenient synthesis of heteroaryl-linked benzimidazoles via microwave-assisted boronate ester formation

Rheault, Tara R.,Donaldson, Kelly H.,Cheung, Mui

experimental part, p. 1399 - 1402 (2009/06/08)

N-Substituted 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-benzimidazoles were conveniently accessed via microwave-assisted synthesis. Subsequent Suzuki-Miyaura cross-coupling with heteroaryl halides proceeded to give a wide variety of heteroaryl-su
