반응 단계

74.08 g (305.7 mmol) of tert-butyl N′-(1-methyl-heptylidene)-hydrazinecarboxylate are dissolved in a mixture of 235 ml of THF and 310 ml of methanol and, after 22.34 g (354.6 mmol) of sodium cyanoborohydride have been added, the mixture is stirred for 1 hour at room temperature. 213 ml of 6N HCl are added dropwise and, after the addition has ended, the mixture is refluxed for 1.5 hours. It is neutralized with 6N NaOH solution, then, after the non-aqueous solvents have been removed, extracted three times with dichloromethane, and, after the mixture has been dried over sodium sulphate, the solvent is removed in vacuo. This gives 37.5 g (85%) of a yellow oil.
