Microwave irradiation promoted the high-yield cyclocondensation of ortho esters (1a-f) with 2-(2-aminophenyl)benzimidazole (2), as the catalyst was no longer needed.
Microwave assisted synthesis of fused benzimidazoles

experimental part, p. 1591 - 1594 (2012/04/10)
Microwave assisted synthesis of some benzimidazo[1,2-c]-quinazolines and benzimidazo[1,2-c][1,2,4]triazolo[4,3-a]quinazolines from the reaction of suitable functionalized benzimidazole and benzimidazoquinazolines with triethylorthoesters in solvent-free conditions is described. In comparison with classical conditions the reactions are faster and the yields are higher under microwave irradiation.
