Procedure

Into a stirred solution of 1-(2-propenyl)-4-tert-butyloxycarbonyl-2-piperazinone (11 g, 46 mmol) in EtOAc (100 mL) at 0° C. was bubbled HCl gas for 10 min. The mixture was stirred at 0° C. for 30 min and then at ambient temperature for 1 h. The solvent was removed in vacuo to yield the hydrochloride salt of the title compound as a white solid. ES MS (M+H)=141.
