4-Amino-3-(trifluoromethyl)benzonitrile → 2-[2-(4-Chloro-phenyl)-5,6-difluoro-benzoimidazol-1-yl]-N-(4-cyano-2-trifluoromethyl-phenyl)-2-cyclohexyl-acetamide

Participants

Reaction Steps

The title compound was prepared in analogy to example 22, int. d) from [2-(4-chloro-phenyl)-5,6-difluoro-benzoimidazol-1-yl]-cyclohexyl-acetic acid and 4-amino-3-trifluoromethylbenzonitrile. The compound was purified by using a MPLC system (CombiFlash Companion, Isco Inc.) eluting with a gradient of heptane to n-heptane/ethyl acetate (1:0 to 4:1 v/v) and subsequent purification by preparative HPLC using a Gemini column and a gradient of acetonitrile:water (containing 0.5% formic acid). Colorless foam (47%). MS (ES+): M+H: 573.2.
