Procedure

The solid (R)-tert-butyl 1-amino-1-oxo-3-(thiophen-2-yl)propan-2-ylcarbamate (448 mg) was dissolved in dioxane (4 mL), aq. 6N HCl (5 mL) was added. After being stirred at room temperature for 1 h, the mixture was concentrated in vacuo to give (R)-2-amino-3-(thiophen-2-yl)propanamide hydrochloride as a solid (337 mg).
