HCID 9095211-Methoxycarbonyl-2-isopropylidene hydrazineYield 89%

Procedure

Hydrazinecarboxylic acid methyl ester (5.01 g) were dissolved in acetone (28 mL), and acetic acid (0.0636 mL) was added. The reaction mixture was stirred at room temperature for 24 hours. Water (50 mL) was added, and mixture was extracted three times with DCM (50 mL) and evaporated under vacuum, giving N′-Isopropylidene-hydrazine-carboxylic acid methyl ester (6.45 g, 89%).
