实验过程

A solution of (S)-2-benzenesulfonylamino-3-{3-benzyloxy-4-[1,1,4-trioxo-5-(2-trimethylsilanylethyl)-1,2,5-thiadiazolidin-2-yl]-phenyl}-propionic acid tert-butyl ester (80 mg, 0.114 mmol) in 12 mL of TFA/CH2Cl2 (5:1) is stirred at RT for 1 h. The solution is concentrated, then four times redissolved in CH2Cl2 and reconcentrated to give the title compound: (M−1)−=644.
