To a stirred solution of benzoic acid hydrazide (2.35 g, 1.73×10-2 mole) and THF (50 ml) was added a solution of methyl isothiocyanate (1.14 g, 1.56×10-2 mole) and THF (50 ml). The reaction was then refluxed for 2 hours before being cooled. The precipitate was collected by filtration and crystallized from ethanol, affording a colorless solid, Mp 199°-200° C.
