Versuchsvorschrift

To the solution of 0.2 g (0.49 mmol) [2-(4-chloro-phenyl)-5,6-difluoro-benzoimidazol-1-yl]-cyclohexyl-acetic acid (example 22, intermediate c)) in 3 ml N,N-dimethylformamide, 0.21 g (0.55 mmol) O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate, 0.42 ml (0.32 g, 2.5 mmol) N-ethyldiisopropylamine and 0.13 g (0.54 mmol) 2-(4-amino-3-fluoro-phenoxy)-2-methyl-propionic acid ethyl ester were added. After 18 h the reaction mixture was poured on water and ethyl acetate, the phases were separated, the organic layer was washed twice with water followed by brine and dried over magnesium sulfate. After filtration the residue was purified by column chromatography on silica gel to give 0.12 g (40%) of the desired compound as light yellow foam.
