Procedure
A solution of 1,1-dimethylethyl 1-[6-chloro-1-(4-{2-[({[(4-methylphenyl)sulfonyl]amino}carbonyl)amino]ethyl}phenyl)-5-(trifluoromethyl)-1H-benzimidazol-2-yl]ethylcarbamate (step 2, 190 mg, 0.28 mmol) in CH2Cl2 (2 ml) was added trifluoroacetic acid (1 ml) and stirred at room temperature for 2 h. The mixture was added water (10 ml) and extracted with CH2Cl2 (20 ml). The organic layer was washed with brine (10 ml), then dried (Na2SO4). After removal of solvent, the crude product was purified by flash column chromatography eluting with CH2Cl2/MeOH (10:1/5:1) to afford 160 mg (99%) of the title compound as white solids.
