A solution of 100 mg (0.35 mmol) of 2-(4-ethylamino-phenyl)-1,1,1,3,3,3-hexafluoro-propan-2-ol and 96 mg (0.35 mmol) of 4-chloromethyl-5-methyl-2-(3-trifluoromethyl-phenyl)-oxazole (example 22.1) in 0.5 mL of DMF was stirred overnight at 80° C. After distribution of the crude mixture between a saturated aqueous solution of NH4Cl and Et2O, the combined organic phases were dried over Na2SO4 and the solvent was evaporated. Column chromatography on silica gel with toluene/EtOAc gave 91 mg (53%) of 2-(4-{ethyl-[5-methyl-2-(3-trifluoromethyl-phenyl)-oxazol-4-ylmethyl]-amino}-phenyl)-1,1,1,3,3,3-hexafluoro-propan-2-ol, yellow solid, MS: 527 (MH+).
