Procedure

To a DCM (500 μL) solution of intermediate (1d) (600 mg, 1.0 mmol) was added TFA (500 μL, 6.4 mmol). The mixture was stirred at room temperature for 30 minutes. Volatiles were removed under vacuum and the TFA salt of the product was lyophilized in 50/50 water/acetonitrile to give the title compound as a white solid (418 mg). Anal. HPLC: retention time=1.2 minutes. Gradient conditions: 25% solvent B/75% solvent A to 95% solvent B/5% solvent B over 6 minutes. MS m/z: [M+H]+ calcd for C23H27ClN4O4S, 491.15; found 473.1 [M+H]+ −18.
