N-methyl-4-o-tolylpyridin-3-amine → 3-Cyano-N-methyl-N-(4-o-tolyl-pyridin-3-yl)-5-trifluoromethyl-benzamide

Participants

Reaction Steps

The title compound was prepared in analogy to example 90, from N-methyl-4-o-tolylpyridin-3-amine (example 1, intermediate a) and 3-cyano-5-trifluoromethyl-benzoic acid after a reaction time of 94 hours. The product was purified by silica gel chromatography using a 10 g column eluting with EtOAc followed by a second chromatography on a 5 g column eluting with a gradient of n-heptane:EtOAc (100:0 to 50:50). Colorless solid (2%). MS (ESI): m/z=396.13 [M+H]+.
