Procedure
3-(2-Methyl-propane-2-sulfinylamino)-3-phenyl-propionic acid methyl ester (1.73 mmol, 1 eq) is dissolved in 10 mL methanol (J. Org. Chem., 2002, 67, 7819-7832). A solution of HCl in dioxane (4 M, 10 mL) is added. The solution is stirred at room temperature for 45 min and concentrated in vacuo. 3-Amino-3-phenyl-propionic acid methyl ester hydrochloride is obtained as yellow viscous oil (135% crude product); ES-MS (MH+)=181.1.
