Reaction Steps

A 67 mg quantity of 1-(2-hydroxyphenyl)-3-[2-(3-isopropoxy-4-methoxyphenyl)oxazol-4-yl]propan-1-one obtained in Example 223 was dissolved in 5 ml of dimethylformamide. A 31 μl quantity of allyl bromide and 73 mg of potassium carbonate were added thereto, and the mixture was stirred at room temperature overnight. A 50 μl quantity of allyl bromide was further added thereto, and the mixture was stirred at 50° C. for 8 hours, and at room temperature overnight. The reaction mixture was added to water, and extraction was then performed with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue was purified by silica gel column chromatography (n-hexane:ethyl acetate 3:1), and crystallized from n-hexane to give 33 mg of colorless powdery 1-(2-allyloxyphenyl)-3-[2-(3-isopropoxy-4-methoxyphenyl)oxazol-4-yl]propan-1-one.
