The title compound was prepared in analogy to example 90, from (2-methanesulfonyl-ethyl)-(4-o-tolyl-pyridin-3-yl)-amine and 2,6-bis(trifluoromethyl)isonicotinic acid (Key Organics Ltd.) after a reaction time of 17 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). A second chromatography (preparative HPLC (phenomenex gemini column), gradient of acetonitrile:water (containing 0.05% formic acid) (10:90 to 98:2)) yielded the desired product as an off-white solid (10%). MS (ESI): m/z=532.11 [M+H]+.
