실험 절차

1.74 g (10 mmol) of 2,2-dimethyl-4-hydroxybutyl-1,3-dioxolane from Example 1a, 3.41 g (13 mmol) of triphenylphosphine, 2.26 g (13 mmol) of diethyl azodicarboxylate and 3.72 g (30 mmol) of 4-methoxyphenol were dissolved in 30 ml of absolute tetrahydrofuran (THF) and boiled under reflux for 1 h. The solvent was removed by distillation, and the residue was chromatographed on silica gel using ethyl acetate (EA)/n-heptane (1:4).
