Procedure

To a solution of methyl 2-(1-(tert-butoxycarbonylamino)ethyl)thiazole-5-carboxylate (0.9 g, 3 mmol) in MeOH (5 mL) was added 4M HCl in dioxane (4 mL). The reaction was stirred overnight at room temperature. The reaction was evaporated to dryness to afford 5-(1-aminoethyl)thiophene-2-carboxylate hydrochloride (0.7 g, 100%).
