Participants

Reaction Steps

The title compound was prepared in analogy to example 90, from [4-(4-fluoro-2-methoxy-phenyl)-pyridin-3-yl]-(tetrahydro-furan-3-ylmethyl)-amine and 3-(methylsulfonyl)-5-(trifluoromethyl)benzoic acid (example 114, intermediate a) after a reaction time of 72 hours at room temperature. The compound was purified by silica gel chromatography on a 20 g column using an MPLC (Flashmaster) system eluting with a gradient of n-heptane:EtOAc (100:0 to 0:100). The resulting brown oil was further purification by preparative HPLC (Gemini NX) with a gradient of MeOH:water (containing 0.05% formic acid) (80:20 to 98:2). Colorless foam (11%). MS (ESI): m/z=553.141 [M+H]+.
