Reaction Steps

0.1 g of N-[2-(3-cyclopropylmethoxy-4-methoxyphenyl)oxazol-4-ylmethyl]-3-hydroxypicolinamide obtained in Example 45 and 0.16 g of cesium carbonate were dissolved in 4 ml of acetonitrile, and 0.2 g of 1-bromopropane was added thereto and stirred overnight at room temperature. Water was added to the reaction mixture and extraction was performed with ethyl acetate. The extract was washed with water once, and further washed with saturated aqueous citric acid once. The organic layer was concentrated under reduced pressure, and the obtained residue was purified by silica gel column chromatography, yielding 72 mg of white powdery N-2-(3-cyclopropylmethoxy-4-methoxyphenyl)oxazol-4-ylmethyl]-3-propoxypicolinamide.
