반응 단계
The title compound was prepared in analogy to Example 4, intermediate, from 2-[2-(4-chloro-phenyl)-5,6-difluoro-benzoimidazol-1-yl]-2-cyclohexyl-ethanol (Ex. 1, int. c), 2-(3-hydroxy-phenoxy)-2-methyl-propionic acid ethyl ester (CAS RN: 328919-24-0), tri-n-butylphosphin and N,N,N′,N′-tetramethylazodicarboxamide. The compound was purified by silica gel chromatography using a MPLC system (CombiFlash Companion, Isco Inc.) eluting with a gradient of n-heptane:ethyl acetate (100:0 to 70:30). Light yellow solid (19%). MS (Turbo Spray): m/z=597.2 [M+H].
