実験手順
4-[2-(tert-Butyl-dimethyl-silanyloxy)-ethoxy]-1-[(5-chloro-pyridin-2-ylcarbamoyl)-methyl]-1H-benzoimidazole-2-carboxylic acid (1-isopropyl-piperidin-4-yl)-amide was prepared by a procedure according to example 108 (v) starting from 670.0 mg (1.45 mmol) 4-[2-(tert-Butyl-dimethyl-silanyloxy)-ethoxy]-1H-benzoimidazole-2-carboxylic acid (1-isopropyl-piperidin-4-yl)-amide and 362.8 mg (1.45 mmol) 2-bromo-N-(5-chloro-pyridin-2-yl)-acetamide. Final purification by flash-chromatography on silica gel using ethyl acetate as eluent gave the title compound as a brown oil.
