Reaction Steps

(2-Benzo[b]thiophen-2-yl-2-oxo-ethyl)-carbamic acid tert-butyl ester (544 mg, 1.867 mmol) was dissolved into 3 mL of EtOAc and 10 mL of 4.0 M HCl in dioxane was added. The mixture was allowed to stir overnight with a white precipitate forming. The precipitate was triturated with 3×10 mL of EtOAc and dried under vacuum to give 400 mg, 94.7% of crude 2-amino-1-benzo[b]thiophen-2-yl-ethanone HCl salt. The material was carried on without further purification.
