실험 절차

Sodium hydride (60%, oily, 190 mg) was added to a solution of 1-[6-(5-methyl-2-phenyl-4-oxazolylmethoxy)-3-pyridylmethyl]-4-phenyl-3-pyrrolecarbaldehyde (1.05 g) and ethyl diethylphosphonoacetate (1.05 g) in N,N-dimethylformamide (50 ml) at 0° C., and the mixture was stirred at 0° C. for 2 hours. The reaction mixture was poured into water, and the precipitated crystals were collected by filtration to obtain ethyl(E)-3-[1-[6-(5-methyl-2-phenyl-4-oxazolylmethoxy)-3-pyridylmethyl]-4-phenyl-3-pyrrolyl]propenoate. The crystals were dissolved in ethanol (80 ml), and hydrogenated on 5% palladium-carbon (800 mg) at room temperature under a normal pressure. The catalyst was filtered, and the filtrate was concentrated. The residue was subjected to silica gel column chromatography to obtain ethyl 3-[1-[6-(5-methyl-2-phenyl-4-oxazolylmethoxy)-3-pyridylmethyl]-4-phenyl-3-pyrrolyl]propionate (1.05 g, yield: 86%) as a colorless oily substance from the fraction eluted with ethyl acetate-hexane (1:2, volume 5 ratio).
