Versuchsvorschrift
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 2,6-bis(trifluoromethyl)isonicotinic acid (Key Organics Ltd.) after a reaction time of 48 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). Light yellow solid (55%). MS (ESI): m/z=515.114 [M+H]+.
