A mixture of N-(trans-4-trifluoromethyl-cyclohexyl)-2-{2,6-dichloro-3-[(tert.-butoxycarbonylamino)-methyl]-phenylamino}-6-[3-aza-bicyclo[3.1.0]hex-1-yl]-1-methyl-1H-benzimidazole-5-carboxylic acid amide (compound 185, 3.3 g, 4.7 mmol), 6 mL 4M HCl in dioxane, 10 mL dioxane and 5 mL 2-propanol is stirred overnight. The resulting precipitate is collected by filtration, diluted with EtOAc and washed with 1N aq NaOH. The organic phase is dried with Na2SO4, filtered and concentrated.
