Participants

Reaction Steps

8.9 g of 1-ethoxalyl-2-(4-aminophenyl)hydrazine and 3.0 g of methyl isothiocyanate were added to 75 ml of ethanol, followed by refluxing for 3.5 hours under heating. The refluxed product was left to stand for cooling and the precipitated crystal was collected by filtration, washed with ethanol and then dried to obtain 8.6 g of 1-ethoxalyl-2-[4-(3-methylthioureido)phenyl]hydrazine (intermediate A) having a melting point of 168°-169° C.
