Procedure

A solution of 10 g (22.8 mmol) dilinalyl phthalate (prepared by the procedure of Example 1) in 100 mL tetrahydrofuran was treated with 2 g palladium on charcoal catalyst and hydrogenated quickly at 40 psi. A small amount of cleavage gave some phthalic acid byproduct, so the mixture was chromatographed on silica gel to give 7.1 g (70% yield) of pure viscous liquid Compound 6, confirmed by its nmr spectrum.
