C-{4-[4-(3-trifluoromethyl-phenyl)-1H-imidazole-2-yl]-cyclohexyl}-methylamine (326 mg, 1.0 mmol, from Example 1C) and TEA (102 mg, 1.0 mmol) were dissolved in CH2Cl2/THF (1:1) and brought to 0° C. with an ice bath. Acetyl chloride (79 mg, 1.0 mmol) was added to the reaction mixture slowly and the ice bath was removed. After 2 hours, the solution was diluted with CH2Cl2, added to a separatory funnel and washed with 10% NaOH (3×). The solution was dried (Na2SO4), concentrated under reduced pressure, and the residue purified using flash chromatography (5%→10% MeOH/CH2Cl2) to give (N-{4-[4-(3-Trifluoromethyl-phenyl)-1H-imidazol-2-yl]-cyclohexylmethyl}-acetamide.
