To a solution of 154 mg (0.3 mmol) of N-(2-benzoyl-4-chloro-phenyl)-2-(3,5-bis-trifluoromethyl-phenyl)-isobutyramide in 1 ml dimethylformamide were added 26 mg (0.6 mmol) sodium hydride (55% suspension in mineral oil). After 30 min stirring at room temperature 85 mg of methyl iodide (0.6 mmol) were added and the reaction mixture was stirred at 80° C. overnight. The solvent was evaporated under reduced pressure and the residue was purified by flash chromatography to yield 51 mg (32%) of the title compound as white crystals. M.p. 89-91° C.
