Methylhydrazine → N-(5-Cyclobutyl-1,3,4-thiadiazol-2-yl)-1-methylhydrazine-1-carboxamide

Participants

Reaction Steps

A solution of methylhydrazine (0.3 mole) in methylene chloride (150 ml) is charged into a glass reaction vessel equipped with a mechanical stirrer, thermometer and reflux condenser. 5-Cyclobutyl-1,3,4-thiadiazol-2-yl isocyanate dimer (0.1 mole) is then added, with stirring, at room temperature. After the addition is completed the reaction mixture is heated at reflux for a period of about 4 hours. After this time the reaction mixture is stripped of solvent and excess hydrazine to yield the desired product 2-methyl-4-(5-cyclobutyl-1,3,4-thiadiazol-2-yl)semicarbazide.
