Participants

Reaction Steps

The title compound was prepared in analogy to example 90, from [4-(4-fluoro-2-methoxy-phenyl)-pyridin-3-yl]-methyl-amine (example 129, intermediate) and 2-methoxy-6-trifluoromethyl-isonicotinic acid after a reaction time of 64 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 (33%). MS (ESI): m/z=436.13 [M+H]+.
