Procedure
1-[(5-Chloro-pyridin-2-ylcarbamoyl)-methyl]-4-(4,4-difluoro-piperidine-1-carbonyl)-1H-benzoimidazole-2-carboxylic acid (1-isopropyl-piperidin-4-yl)-amide was prepared by a procedure according to example 22 starting from 870 mg (1.70 mmol) 1-[(5-Chloro-pyridin-2-ylcarbamoyl)-methyl]-2-(1-isopropyl-piperidin-4-ylcarbamoyl)-1H-benzoimidazole-4-carboxylic acid and 302.3 mg (1.87 mmol) 4,4-difluoro-piperidine-hydrochloride. The title compound was obtained as its formiate. Subsequent transformation to the corresponding acetate gave a white amorphous solid.
