3,5-Bis(trifluoromethyl)benzoyl chloride → N-[4-(2-Chloro-phenyl)-pyridin-3-yl]-N-(2-fluoro-ethyl)-3,5-bis-trifluoromethyl-benzamide

Participants

Reaction Steps

The title compound was prepared in analogy to example 72, intermediate, from [4-(2-chloro-phenyl)-pyridin-3-yl]-(2-fluoro-ethyl)-amine and 3,5-bis(trifluoromethyl)benzoyl chloride (CAS RN 1271-19-8) and using a gradient of n-heptane:EtOAc (100:0 to 50:50) for the chromatographic purification to give a first batch of compound (light yellow solid). A second chromatographic purification of the remaining impure fractions and mother liquor gave a second batch of compound. Yellow solid (25% overall). MS (ESI): m/z=491.08 [M+H]+.
