TFA (0.5 mL) was added to a solution of 2-acetylsulfanylmethyl-3-(2-tert-butoxycarbonylamino-pyridin4-yl)-propionic acid ethyl ester (50 mg, 0.13 mmol) in methylene chloride under argon. The solution was stirred for 60 min and concentrated under reduced pressure to give crude 2-acetylsulfanylmethyl-3-(2-amino-pyridin-4-yl)-propionic acid ethyl ester (52 mg, 100%).
