Procedure

The title compound was prepared in analogy to example 90, from [4-(4-fluoro-2-methoxy-phenyl)-pyridin-3-yl]-(3-methyl-oxetan-3-ylmethyl)-amine and 2,6-bis(trifluoromethyl)isonicotinic acid (Key Organics Ltd.) after a reaction time of 16 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) followed by a second chromatography using preparative HPLC (Gemini NX column) and a gradient of methanol:water (containing 0.1% formic acid) (20:80 to 98:2) as eluant. Colorless solid (12%). MS (ESI): m/z=544.15 [M+H]+.
