실험 절차

A mixture of 15.55 g of 4-[(2-ethyl-4-tetradecylphenoxy)methyl]-2,2-dimethyl-1,3-dioxolane, 10 ml of 5% hydrochloric acid and 300 ml of tetrahydrofuran was heated at reflux for 4 hours, then cooled and 1/2 of the solvent evaporated at reduced pressure. The remainder was diluted with ethyl acetate, washed with aqueous sodium bicarbonate, dried and the solvents evaporated. The residue was chromatographed on silica gel, eluting first with hexane:ethyl acetate (8:1), then (4:1), giving 12.1 g of the desired compound, mp 55°-56° C.
