Reaction Steps

To a mixture of tert-butyl 2-oxo-2-(thiophen-3-yl)ethylcarbamate (776 mg, 3.21 mmol) in Et2O (3 mL) was added a HCl solution (4.0 M in dioxane, 6 mL) at 0° C. After stirring at 0° C. for 10 min, the resulting mixture was allowed warmed up to room temperature and stirred for 2 h. The reaction mixture was evaporated under vacuum to provide the titled compound (570 mg, quantitative) as a white solid. MH+142.
