Versuchsvorschrift

The title compound was prepared in analogy to example 90, from methyl-[2-(2,2,2-trifluoro-ethoxy)-[3,4]bipyridinyl-3′-yl]-amine and 3-(methylsulfonyl)-5-(trifluoromethyl)-benzoic acid (example 114, intermediate a) after a reaction time of 18 hours. The reaction mixture was poured on saturated aqueous NH4Cl solution and CH2Cl2 and the layers were separated. The aqueous layer was extracted three times with CH2Cl2. The organic layers were dried over MgSO4, filtered, treated with silica gel and evaporated. The compound was purified by silica gel chromatography on a 20 g column using an MPLC (ISCO) system eluting with EtOAc (isocratic). Further purification by preparative HPLC (Gemini NX column) using a gradient of MeOH:water (containing 0.1% formic acid) (20:80 to 98:2). Colorless foam (41%). MS (ESI): m/z=534.09 [M+H]+.
