実験手順
The title compound was prepared in analogy to example 90, from [4-(2-chloro-phenyl)-pyridin-3-yl]-methyl-amine (prepared according to DE10008042) and 3-(methylsulfonyl)-5-(trifluoromethyl)benzoic acid (example 114, intermediate a) after a reaction time of 18 hours at room temperature. The compound was purified by silica gel chromatography on a 20 g column using an MPLC system (CombiFlash Companion, Isco Inc.) eluting with a gradient of n-heptane:EtOAc (100:0 to 0:100). Another purification step using preparative HPLC (Gemini NX column) with a gradient of MeOH:water (containing 0.05% formic acid) (80:20 to 98:2) gave the desired compound as a colorless foam (26%). MS (ESI): m/z=469.060 [M+H]+.
