Participants

Reaction Steps

The title compound was prepared in analogy to example 90, from 2-(4-(4-fluoro-2-methoxyphenyl)pyridin-3-ylamino)acetonitrile and 3-(methylsulfonyl)-5-(trifluoromethyl)benzoic acid (example 114, intermediate a) after a reaction time of 18 hours. 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). Light brown solid (51%). MS (ESI): m/z=508.096 [M+H]+.
