Procedure

The product of Example-I-4, S-[2-[[(1,1-dimethylethoxy)carbonyl]amino]ethyl]-2-methyl-L-cysteine trifluoroacetate, (5.5 g, 14.0 mmol) was dissolved in 1 N HCl (100 mL) and stirred at room temperature under nitrogen overnight. The solution was removed by freeze-drying to give the title S-(2-aminoethyl)-2-methyl-L-cysteine hydrochloride, 1H NMR?(DMSO-d6/D2O)? 1.43 (s, 3H), 2.72 (m, 2H), 2.85 (d, 1H), 2.95 (t, 2H), 3.07 (d, 1H). m/z [M+H+] 179.
