Reaction Steps

A 0.15 g quantity of the N-[2-(3-hydroxy-4-methoxy phenyl)oxazol-4-ylmethyl]-3-methylpicolinamide obtained in Example 17 and 0.18 g of potassium carbonate were dissolved in 4 ml of dimethylformamide, and 0.19 g of 1,1,1-trifluoro-2-iodoethane was added thereto. The mixture was stirred with heating at 80° C. overnight. The reaction mixture was allowed to cool, water was then added thereto, and extraction was performed with ethyl acetate. The extract was washed with water twice, and the organic layer was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=3:1) to give 0.11 g of white powdery N-{2-[4-methoxy-3-(2,2,2-trifluoroethoxy)phenyl]oxazol-4-ylmethyl}-3-methylpicolinamide.
