Hydrochloric acid (1.8 mL, 7.4 mmol, 4 M in 1,4-dioxane) was added to a solution of 4-tert-butyloxycarbonyl-1-(2-hydroxyethyl)-piperazin-2-one (0.45 g, 1.8 mmol) in 1,4-dioxane (5.0 mL). The mixture was stirred overnight and concentrated to give 1-(2-hydroxyethyl)-piperazin-2-one hydrochloride as an off-white solid (0.30 g, 91%).
