Abstract A new one-pot neat synthesis of some 5-aryl-2,4-dihydro-3H-1,2,4-triazol-3-ones through cyclocondensation of ethyl carbazate with aryl nitriles catalyzed by DMAP as an efficient and basic nucleophilic catalyst is described.

Key words： 1,2,4-Triazol-3-ones One-pot synthesis DMAP Aryl nitriles
