Reaction Steps

First, 14 g of phenyl hydrazine hydrochloride and 200 ml, of carbon tetrachloride were put into a 500-mL three-neck flask, 30 mL of triethylamine (Et3N) was added dropwise to the mixture little by little, and the mixture was stirred at room temperature for 1 hour. After a predetermined time elapsed, 17 g of N-(1-ethoxybenzylidene)butyramide obtained in Step 1 of Synthesis Example 1 was added to this mixture, and the mixture was stirred at room temperature for 24 hours. After the stirring, this mixture was dissolved in chloroform and washed with water and saturated saline. After the washing, anhydrous magnesium sulfate was added to the organic layer for drying. This mixture was gravity-filtered, and the obtained filtrate was concentrated to give an oily substance. This oily substance was purified by silica gel column chromatography. As the developing solvent, toluene was used. The obtained fraction was concentrated, so that 1,3-diphenyl-5-propyl-1H-1,2,4-triazole (abbreviation: HPrp3tz1-Ph) was obtained (a red oily substance, 29% yield). The synthesis scheme of Step 1 is shown in (C-1) below.
