Versuchsvorschrift
A mixture of 4.5 g (29.8 mmol) of 4-aminobenzoic acid hydrazide and 2.6 mL of ethylthioisocyanate in 15 mL of acetonitrile was heated at reflux for 3 hours. The solution was cooled to 24° C., and the precipitate was collected by filtration and dried under vacuum to afford 7.0 g of 1-(4-aminobenzoyl)-4-ethylthiosemicarbazide, mp 113°-115° C.
