Reaction Steps
A mixture of cyclopentanone (20 g, 238 mmol) and hydrazinecarboxylic acid tert-butyl ester (31.4 g, 0.238 mol) in MeOH (300 mL) was stirred at RT for 2 h. The reaction mixture was concentrated in vacuo and the resulting solid was dried under vacuum to give 1-cyclopentylidenehydrazine-2-carboxylic acid tert-butyl ester (47.1 g, 100% yield).
