실험 절차

To a solution of tert-butylcarbazate (50.0 g, 378 mmol) in 40 mL acetone is added 10 g MgSO4 and 5 mL acetic acid and the reaction mixture is stirred at reflux temperature for 1 h. The reaction mixture is filtered and concentrated in vacuo. The residue is crystallized from diethyl ether/cyclohexane. Yield: 49.4 g.
