实验步骤: The title compound was prepared in analogy to Example 26, intermediate, from 2-[2-(4-chloro-phenyl)-5,6-difluoro-benzoimidazol-1-yl]-2-cyclohexyl-ethanol (Example 1, intermediate c) and 4-bromomethyl-3-fluorobenzoic acid methyl ester (commercially available) to give the compound as light yellow solid (34%). MS (Turbo Spray): m/z=557.4 [M+H].

反应条件: temp:65.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of methyl 4-(bromomethyl)-3-fluorobenzoate (18 g, 73 mmol) in MeOH (150 ml) was added the solution of NaCN (7.2 g, 146 mmol) in H2O (40 ml). The mixture was stirred at 65° C. for 5 hours. Most of MeOH was evaporated and additional water was added and extracted by EtOAc (200 ml×3), dried with anhydrous Na2SO4, filtered and evaporated to give the crude product. Purification by column chromatography (PE/EtOAc=50/1 to 10/1) gave the product (8 g, 63.8%). Most of MeOH was evaporated additional water was added extracted by EtOAc (200 ml×3) dried with anhydrous Na2SO4 filtered evaporated to give the crude product Purification by column chromatography (PE/EtOAc=50/1 to 10/1)
