Versuchsvorschrift
The title compound was prepared in analogy to example 90, from [4-(4-fluoro-2-methoxy-phenyl)-pyridin-3-yl]-(2,2,2-trifluoro-ethyl)-amine (example 133, intermediate a) 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 CH2Cl2: EtOAc (100:0 to 85:15). Light yellow foam (43%). MS (ESI): m/z=551.087 [M+H]+.
