Versuchsvorschrift
The title compound was prepared in analogy to example 90, from [4-(4,5-difluoro-2-methoxy-phenyl)-pyridin-3-ylamino]-acetic acid methyl ester (example 172, intermediate a) and 2,6-bis(trifluoromethyl)isonicotinic acid (Key Organics Ltd.) after a reaction time of 72 hours. The compound was purified by silica gel chromatography using a MPLC system (CombiFlash Companion, Isco Inc.) eluting with a gradient of n-heptane:EtOAc (100:0 to 0:80). Colorless solid (48%). MS (ESI): m/z=550.102 [M+H]+.
