The title compound was prepared in analogy to example 90, from (2-methoxy-[3,4′]bipyridinyl-3′-ylamino)-acetic acid methyl ester (example 178, intermediate) and 3-methanesulfonyl-5-trifluoromethyl-benzoic acid (example 114, intermediate a) after a reaction time of 72 hours. The compound was purified by silica gel chromatography using a MPLC system (CombiFlash Companion, Isco Inc.) eluting with a gradient of n-heptane:EtOAc (100:0 to 20:80). The product-containing fractions were pooled and evaporated. The remaining solid was purified by preparative HPLC (Gemini NX column) with a gradient of methanol:water (containing 0.05% formic acid) (80:20 to 98:2). Light yellow foam (32%). MS (ESI): m/z=524.108 [M+H]+.
