실험 절차
Under a blanket of nitrogen, 8.8 g (0.087 mol) 2,4-dichlorobenzoyl chloride was added to a solution of 23.0 g (0.087 mol) 4-octoxybenzoyl hydrazine and 12.13 ml (8.8 g, 0.087 mol) freshly distilled triethylamine in 348 ml dry chloroform. After about one hour of stirring a dense white precipitate of the required product was formed. Stirring was continued until the next day. The product was collected by filtration and recrystallized from ethanol/water to give 31 g (81.5% yield) of 2,5-dichloro-N′-[4-(octyloxy)benzoyl]benzohydrazide as a white solid.
