A mixture of 4-bromo-N′-methylbenzimidohydrazide hydrochloride 1 (1.7 g) (prepared according to a procedure in synthesis of Sch-1499895) in acetic anhydride (10 ml) was heated at 100° C. for 0.5 hour. After cooling and concentration under reduced pressure, the residue was dissolved in EtOAc, washed with saturated NaHCO3 twice, brine and dried (MgSO4). After evaporation of solvent, the residue was purified on silica gel. Elution with EtOAc gave 3-(4-bromophenyl)-1,5-dimethyl-1H-[1,2,4]-triazole 2BK (1.04 g).
