2,6-Bis(trifluoromethyl)pyridine-4-carboxylic acid → N-[4-(4,5-Difluoro-2-methoxy-phenyl)-pyridin-3-yl]-N-(2-methanesulfonyl-ethyl)-2,6-bis-trifluoromethyl-isonicotinamide

Participants

Reaction Steps

The title compound was prepared in analogy to example 90, from [4-(4,5-difluoro-2-methoxy-phenyl)-pyridin-3-yl]-(2-methanesulfonyl-ethyl)-amine and 2,6-bis(trifluoromethyl)isonicotinic acid (Key Organics Ltd.) after a reaction time of 15 hours. The compound was purified by silica gel chromatography on a 10 g column using a MPLC system eluting with a gradient of n-heptane:EtOAc (100:0 to 0:100). Brown solid (42%). MS (ESI): m/z=584.09 [M+H]+.
