Procedure
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) and 3-hydroxy-4-methyl-benzoic acid ethyl ester and replacing di-ethyl azodicarboxylate by di-tert-butyl azodicarboxylate. White solid (16%). MS (Turbo Spray): m/z=539.2 [M+H].
