HCID 86670759N-[4-(4-Fluoro-2-methoxy-phenyl)-pyridin-3-yl]-N-(2,2,2-trifluoro-ethyl)-2,6-bis-trifluoromethyl-isonicotinamide

Procedure

The title compound was prepared in analogy to example 90, from [4-(4-fluoro-2-methoxy-phenyl)-pyridin-3-yl]-(2,2,2-trifluoro-ethyl)-amine (example 133, intermediate a) and 2,6-bis(trifluoromethyl)isonicotinic acid (Key Organics Ltd.) after a reaction time of 96 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 (44%). MS (ESI): m/z=542.09 [M+H]+.
