実験手順

Sodium hydride (60%, oily, 36.0 mg) was added to a solution of ethyl 3-[1-(6-hydroxy-2-naphthylmethyl)-4-phenyl-3-pyrrolyl]propionate (360 mg) in N,N-dimethylformamide (10 ml) at 0° C., and the mixture was stirred at room temperature for 30 minutes. 4-Chloromethyl-5-methyl-2-phenyloxazole (207 mg) was added to the mixture, which was stirred at room temperature for 1 hour. The reaction mixture was poured into water, which was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated aqueous sodium chloride solution, dried (MgSO4), and concentrated. The residue was subjected to silica gel column chromatograpy, and ethyl 3-[1-[6-(5-methyl-2-phenyl-4-oxazolylmethoxy)-2-naphthylmethyl]-4-phenyl-3-pyrrolyl]propionate (304 mg, yield: 59%) was obtained as an oily substance from the fraction eluted with ethyl acetate-hexane (1:3, volume ratio).
