Versuchsvorschrift
The title compound was prepared in analogy to example 90, from [4-(4,5-difluoro-2-methoxy-phenyl)-pyridin-3-yl]-methyl-amine (example 130, intermediate) and 2,6-bis(trifluoromethyl)isonicotinic acid (Key Organics Ltd.) after a reaction time of 23 hours. The compound was purified by silica gel chromatography on a 20 g column using a MPLC system eluting with a gradient of n-heptane:EtOAc (100:0 to 0:100). Light brown solid (38%). MS (ESI): m/z=492.10 [M+H]+.
