Procedure
To a solution benzyl 7-(2-benzyloxy-5-formyl-3,4,6-trimethylphenyl)-7-(4-fluorophenyl)heptanoate (2.3 g) in dioxane (20 ml) and water (2 ml) was added silver oxide (II) (4.5 g) and the mixture was stirred for 12 days. Insoluble materials were filtered off and washed with ethyl acetate. The washing was combined with the filtrate and the mixture was concentrated. Ethyl acetate was added and the mixture was washed with water and saturated saline and dried with anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure and the residue was subjected to silica gel column chromatography to obtain benzyl 7-(2-benzyloxy-5-carboxy-3,4,6-trimethylphenyl)-7-(4fluorophenyl)heptanoic acid (1.5 g) (Compound 68). The physical properties and spectrum data thereof are shown in Tables 3 and 4.
