実験手順

10% Palladium on carbon (0.05 g) was added to a solution of methyl 6-(benzenesulphonylmethyl)-2-(3-t-butyoxycarbonylamino-prop-1-yn-1-yl)-3-(furan-3-yl)benzoate (Intermediate 132, 0.22 g) in ethanol (10 ml) and THF (10 ml) and the mixture was stirred at room temperature in an atmosphere of hydrogen (balloon) for 60 hours. 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 and cyclohexane with a gradient of 25-60% to give methyl 6-(benzenesulphonylmethyl)-2-(3-t-butoxycarbonylaminopropyl)-3-(furan-3-yl)benzoate (0.115 g) as a colourless gum.
