HCID 683129781-Tert-butyl-4-hydrazinylpiperidine hydrochlorideYield 100%

Procedure

A mixture of tert-butyl 2-(1-tert-butylpiperidin-4-yl)hydrazinecarboxylate (350 mg, 1.29 mmol) in sat. HCl/EtOAc solution (20 mL) was stirred at room temperature overnight. The solvent was removed under reduce pressure to afford 1-tert-butyl-4-hydrazinylpiperidine hydrochloride (268 mg, 100% yield), which was used in the next step without further purification. LCMS (ESI) m/z: 172.3 [M+H+].
