Versuchsvorschrift
N′-[1-(4-Fluorophenyl)propylidene]-4-methylbenzenesulfonohydrazide (12.0 g) was dissolved in thionyl chloride (30 ml), and the mixture was stirred at room temperature for 1 hr. The reaction mixture was poured into a 1N aqueous sodium hydroxide solution. The precipitated solids were collected by filtration, washed with water and dried with airflow to give 4-(4-fluorophenyl)-5-methyl-1,2,3-thiadiazole (6.19 g, 65%) as a yellow solid.
