Hydrochloric Acid → (4S,7S,10aS)-4-amino-5-oxo-N-(thiazol-2-yl)octahydro-2H-pyrido[2,1-b][1,3]thiazepine-7-carboxamide hydrochloride salt

Participants

Reaction Steps

To a round bottom flask was added tert-butyl (4S,7S,10aS)-5-oxo-7-(thiazol-2-ylcarbamoyl)octahydro-2H-pyrido[2,1-b][1,3]thiazepin-4-ylcarbamate (35 mg, 0.082 mmol) and 4 M HCl in dioxane (1 mL). The mixture was stirred at rt for 1 h. The reaction mixture was concentrated to give (4S,7S,10aS)-4-amino-5-oxo-N-(thiazol-2-yl)octahydro-2H-pyrido[2,1-b][1,3]thiazepine-7-carboxamide hydrochloride salt (30 mg, 0.082 mmol, 100% yield).
