Versuchsvorschrift
Following procedures similar to those employed in Step A of Example 2, the reaction of 10.0 g (0.0653 mole) of 4-fluorophenyl isothiocyanate with 3.01 g (0.0654 mole) of methylhydrazine in 100 ml of ethanol yielded 10 g of 4-(4-fluorophenyl)-2-methyl-3-thiosemicarbazide as a solid, mp 148°-150° C. The nmr spectrum was consistent with the proposed structure.
