Procedure
To a solution of (2-{3-benzyloxy-4-[1,1,4-trioxo-5-(2-trimethylsilanylethyl)-1,2,5-thiadiazolidin-2-yl]-benzyl}-phenyl)-carbamic acid tert-butyl ester (1.7 g, 2.73 mmol) in methylene chloride (10 mL) is added TFA (5 mL) and the mixture is stirred at RT for 20 min. The solvent is removed under reduced pressure and methylene chloride is added to the residue and evaporated (6×) to give the title compound as its TFA salt.
