TFA (0.5 mL) was added to a solution of 2-acetylsulfanylmethyl-3-(6-tert-butoxycarbonylaminopyridin-3-yl)-propionic acid ethyl ester (100 mg, 0.26 mmol) in methylene chloride (2 mL) under argon. The solution was stirred for 60 min and concentrated under reduced pressure to give crude 2-acetylsulfanylmethyl-3-(6-amino-pyridin-3-yl)-propionic acid ethyl ester (104 mg, 100%).
