Versuchsvorschrift
The title compound was prepared in analogy to example 90, from [2-(3-methylamino-pyridin-4-yl)-phenyl]-acetonitrile and 3,5-bis(trifluoromethyl)benzoic acid (CAS RN 725-89-3) after a reaction time of 5 days. 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 50:50) followed by a second chromatography, using preparative HPLC (Phenomenex Gemini® column, gradient of methanol:water (10:90 to 95:5)). Colorless solid (3%). MS (ESI): m/z=464.118 [M+H]+.
