3-Fluoro-5-(trifluoromethyl)benzoyl chloride → 3-Fluoro-N-[4-(4-fluoro-2-methoxy-phenyl)-pyridin-3-yl]-N-methyl-5-trifluoromethyl-benzamide

Participants

Reaction Steps

The title compound was prepared in analogy to example 72, intermediate, from [4-(4-fluoro-2-methoxy-phenyl)-pyridin-3-yl]-methyl-amine and 3-fluoro-5-(trifluoromethyl)benzoic acid chloride (CAS RN 171243-30-4). The compound was purified by silica gel chromatography using a MPLC system (CombiFlash Companion, Isco Inc.) eluting with a gradient of n-heptane:EtOAc (100:0 to 0:100). The product-containing fractions were pooled and evaporated. The yellow solid was further purified by preparative HPLC (Phenomenex Gemini® column) with a gradient of acetonitrile:water (containing 0.05% formic acid) (50:50 to 95:5). Light yellow solid (23%). MS (ESI): m/z=423.113 [M+H]+.
