Procedure
A mixture of N-(4-bromo-phenyl)-2-(2-chloro-5-{[(tert-butoxycarbonyl)-amino]-methyl}-phenylamino)-6-(2,2-difluoro-ethoxy)-1-methyl-1H-benzimidazole-5-carboxylic acid amide (1.35 g; 2.03 mmol) and TFA (3.47 g; 30.5 mmol) in DCM (75 mL) was stirred over night at rt. The mixture was cooled to 0° C. and basicified to pH ˜10 and extracted with DCM. The organic extracts were dried over Na2SO4, filtered and concentrated. The residue was washed with a mixture of Et2O and petroleum ether to give the sub-title compound.
