A mixture of methyl 6-(bicyclo[2.2.2]oct-5-ene-2-ylsulphonylmethyl)-3-(furan-3-yl)-2-methoxybenzoate (Intermediate 170, 0.26 g) and palladium on carbon (10%, 0.01 g) in THF (15 ml) and ethanol (10 ml) was stirred in an atmosphere of hydrogen (balloon) for 1 hour. The mixture was filtered through Celite and the filtrate was evaporated to dryness. The residue was purified by chromatography on silica, eluting with a mixture of ethyl acetate in cyclohexane with a gradient of 10-50% to give methyl 6-(bicyclo[2.2.2]octane-2-ylsulphonylmethyl)-3-(furan-3-yl)-2-methoxybenzoate (0.029 g).
