Reaction Steps
(S)-2-tert-Butoxycarbonylamino-3-[4-(2,3-dimethyl-pyridin-4-yloxy)-phenyl]-propionic acid methyl ester (0.2 g) was taken in 4 mL of DCM and cooled to 0° C. and HCl (1 mL, 4N in dioxane) was added and reaction was stirred at room temperature for 2 hours. All volatiles were evaporated and residue was triturated with DCM/hexanes (0.17 g). LCMS (m/z): 302.
