実験手順
The title compound was prepared in analogy to example 90, from (2,2-difluoro-ethyl)-[4-(4,5-difluoro-2-methoxy-phenyl)-pyridin-3-yl]-amine and 2,6-bis(trifluoromethyl)isonicotinic acid (Key Organics Ltd.) after a reaction time of 66 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 50:50). Light brown solid (66%). MS (ESI): m/z=542.09 [M+H]+.
