Procedure
The title compound was prepared in analogy to example 90, from N-methyl-4-o-tolylpyridin-3-amine (example 1, intermediate a) and 3,4,5-trifluorobenzoic acid (CAS RN 121602-93-5) after a reaction time of 64 hours. The compound was purified by silica gel chromatography on a 10 g column using a MPLC system eluting with a gradient of n-heptane:EtOAc (100:0 to 50:50). The product-containing fractions were pooled and evaporated. The resulting brown solid was chromatographed a second time by silica gel chromatography on a 10 g column using a MPLC system eluting with a gradient of n-heptane:EtOAc (100:0 to 50:50). Light brown solid (22%). MS (ESI): m/z=357.12 [M+H]+.
