실험 절차

A solution of 8-bromo-N-(2-chlorophenyl)-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carbohydrazonamide (200 mg, 0.45 mmol) in anhydrous THF (8 mL) was treated with CDI (145 mg, 0.89 mmol) and stirred at room temperature overnight, diluted with water. The solid was washed with water and dried in vacuum to give 3-(8-bromo-4,5-dihydrobenzo[b]thieno[2,3-d]oxepin-2-yl)-4-(2-chlorophenyl)-1H-1,2,4-triazol-5(4H)-one (195 mg, yield: 92%). ESI-MS: 473.96
