Versuchsvorschrift

A solution of pivaloyl chloride (34 mg; 0.28 mmol) in DCM (1 mL) was added dropwise to a mixture of N-(4-bromo-phenyl)-2-(2-chloro-5-{[amino]-methyl}-phenylamino)-6-(2,2-difluoro-ethoxy)-1-methyl-1H-benzimidazole-5-carboxylic acid amide ((see Example 72, step (d)) 150 mg; 0.27 mmol), TEA (41 mg; 0.41 mmol) and DCM (2 mL) at 0° C. The resulting mixture was stirred over night at rt, poured into water and extracted with DCM. The organic extracts were washed with brine, dried over Na2SO4, filtered and concentrated. The residue was recrystallized from EtOAc/petroleum ether to give the title compound.
