Participants

Reaction Steps

A solution of 3-acetylsulfanyl-2-(6-tert-butoxycarbonylamino-pyridin-3-ylmethyl)-butyric acid ethyl ester/B (55 mg; 0.14 mmol) in concentrated HCl (2 mL) was refluxed under argon for 1 hour. The reaction mixture was allowed to cool to room temperature and concentrated under reduced pressure to afford 39.4 mg of the title compound as the hydrochloride salt.
