반응 단계
In 30 ml of tetrahydrofuran were dissolved 3 g of 3-hydroxytetrahydrofuran, 6.5 g of methyl 2-(4-hydroxyphenyl)-2-oxoacetate and 9 g of triphenylphosphine. The thus prepared solution was mixed with 6.5 g of diethyl azodicarboxylate, and the mixture was stirred for 2 hours. After distilling off the solvent, the resulting residue was purified by subjecting it to silica gel column chromatography using dichloromethane as an eluant, thereby obtaining 7.5 g of methyl 2-[4-[(tetrahydro-3-furanyl)oxy]phenyl]-2-oxoacetate in an oily form.
