We have observed an unusual example of cobalt-mediated cyclization of 4-pyridinecarboxaldehyde and 2-nitroaniline to afford 2-(4-pyridyl)benzimidazole under hydro(solvo)thermal conditions. Reaction of Co(NO 3 ) 2 โ…6H 2 O with 4-pyridinecarboxaldehyde and 2-nitroaniline in ethanol at 120ยฐC gave a cob
