Reaction Steps
Hydrazine hydrate (28.0 mL) was dissolved in n-BuOH (200 mL) and cooled in an ice bath. A solution of 2-dimethylaminomethyl-cyclohexanone (64.0 g) in n-BuOH (50 mL) was added dropwise, the mixture was slowly warmed and refluxed for 20 hours. The solvent was evaporated under reduced pressure.
