Procedure

A mixture of 5-chloromethyl-3-(5-methyl-2-phenyl-4-oxazolylmethoxy)isoxazole (457 mg), methyl 2-(3-hydroxyphenyl)acetate (249 mg), anhydrous potassium carbonate (415 mg) and N,N-dimethylformamide (10 mL) was stirred at 60° C. for 3 hrs. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated. The obtained residue was subjected to silica gel column chromatography to give methyl 2-[3-[3-(5-methyl-2-phenyl-4-oxazolylmethoxy)-5-isoxazolylmethoxy]phenyl]acetate as a colorless oil (604 mg, 93%) from a fraction eluted with ethyl acetate-hexane (1:1, v/v).
