Procedure

The title compound was prepared in analogy to Example 90, from 1-[4-(4-fluoro-2-methoxy-phenyl)-pyridin-3-ylamino]-butan-2-one (example 203, intermediate a) and 3-methanesulfonyl-5-trifluoromethyl-benzoic acid (example 114, intermediate a) after a reaction time of 24 hours. The compound was purified by silica gel chromatography on a 20 g column using a MPLC system (CombiFlash Companion, Isco Inc.) 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 (with 0.05% formic acid) (80:20 to 98:2). Light red foam (13%). MS (ESI): m/z=539.126 [M+H]+.
