Procedure

Following procedures similar to those employed in Step A of Example 2, the reaction of 22.3 g (0.0810 mole) of 4-iodo-2-methylphenyl isothiocyanate with 3.74 g (0.0811 mole) of methylhydrazine in 175 ml of ethanol yielded 16.7 g of 4-(4-iodo-2-methylphenyl)-2-methyl-3-thiosemicarbazide as a solid, mp 160°-161° C. The nmr spectrum was consistent with the proposed structure.
