Reaction Steps
Alternatively, 1-Boc-4-[2-(4-pyridinyl)ethyl]piperazine (1.0 g, 3.43 mmol) was dissolved in ethyl ether. Ethyl acetate (15 mL) saturated with HCl was added, and the mixture stirred for 30 min at room temperature. The mixture was concentrated under vacuum and provided 1-[2-(4-pyridinyl)-ethyl]piperazine hydrochloride (900 mg, 87%) as a tan solid.
