실험 절차

8 Milliliters of acetonitrile was added to 0.63 g of 4-[N-(4-nitrophenyl)amino]-4H-1,2,4-triazole, 0.82 g of 4-bromobenzyl bromide and 0.62 g of anhydrous potassium carbonate and the mixture was stirred for 3 hours at room temperature. The solvent was removed by distillation under reduced pressure, and water was added to the residue obtained, which was then extracted with chloroform. The chloroform layer separated was washed with water and dried over anhydrous magnesium sulfate, and the solvent was removed by distillation. The residue was purified by silica gel column chromatography to give crude crystals from the chloroform/methanol (100/1) eluate. The crude crystals were recrystallized from acetone to give 0.71 g of 4-[N-(4-bromobenzyl)-N-(4-nitrophenyl)amino]-4H-1,2,4-triazole.
