Participants

Reaction Steps

The title compound was prepared in analogy to example 90, from (4-o-tolyl-pyridin-3-ylamino)-acetonitrile and 3,5-bis-trifluoromethyl-benzoic acid (CAS RN 725-89-3) after a reaction time of 18 hours. The compound was purified by silica gel chromatography on a 20 g column using a MPLC system eluting with a gradient of n-heptane:EtOAc (100:0 to 0:100). The product-containing fractions were pooled and evaporated until a suspension formed. The colorless solid was filtered off and washed with a small amount of a mixture of EtOAc:n-heptane (1:6). Colorless solid (37%). MS (ESI): m/z=464.12 [M+H]+.
