Procedure

N-[2-(3-cyclopropylmethoxy-4-methoxyphenyl)oxazol-4-ylmethyl]-2-trifluoromethylbenzamide obtained in Example 25 was dissolved in 1 ml of dimethylformamide. A 30 mg quantity of sodium hydride was added thereto with ice-cooling and stirring, and the mixture was stirred for 30 minutes. A 30 mg quantity of methyl iodide was added thereto, and the reaction mixture was stirred at room temperature for 2 hours. Water and ethyl acetate were then added thereto, and extraction was performed. The organic layer was washed with water twice and concentrated by removing the solvent under reduced pressure. The residue was purified by silica gel chromatography (n-hexane:ethyl acetate=3:1) to give 35 mg of colorless oily N-[2-(3-cyclopropylmethoxy-4-methoxyphenyl)oxazol-4-ylmethyl]-N-methyl-2-trifluoromethylbenzamide.
