Methyl 4-[(1E)-3-(2-methyl-1,3-dioxolan-2-yl)prop-1-enyl]bicyclo[2.2.2]octane-1-carboxylate (4-B) (1.1 g) was stirred in ethanol (75 mL). A spatula tip scoop of 10% Pd on carbon (150 mg) was added. A hydrogen balloon was added and the mixture was stirred under hydrogen atmosphere for 3 h. The palladium-on-carbon was filtered and the ethanol was removed in vacuo to yield methyl 4-[3-(2-methyl-1,3-dioxolan-2-yl)propyl]bicyclo[2.2.2]octane-1-carboxylate (4-C).
