실험 절차

Fifty grams (0.33 mole) of 2-fluorophenylisothiocyanate and 20 g. (0.33 mole) of formylhydrazine were refluxed for 7 hours in 500 ml. of tetrahydrofuran (THF). The reaction mixture was allowed to cool and the insoluble product was collected by filtration. The crude product was washed with water, filtered and dried. The yield was 10 g. of 1-formyl-4-(2-fluorophenyl)-3-thiosemicarbazide, mp. about 148°-149° C.
