実験手順
Hydrogen chloride (4M in dioxane, 2 ml) was added to a solution of 6-(benzenesulphonylmethyl)-2-[2-(t-butoxycarbonyl)aminoethoxy]-3-(furan-3-yl)benzoic acid (Intermediate 6, 0.018 g) in dioxane (0.5 ml) and the resultant mixture was stirred at room temperature for 2 hours. The mixture was evaporated to dryness and the residue was triturated with ether. The solid was collected by filtration then purified by chromatography on silica, eluting with a mixture of DCM, methanol, acetic acid and water in a ratio of 240:20:3:2 changing to 120:15:3:2. After evaporation of the solvent, the residue was treated with hydrochloric acid (1M) and evaporated to dryness to give 2-(2-aminoethoxy)-6-(benzenesulphonylmethyl)-3-(furan-3-yl)benzoic acid hydrochloride (0.008 g) as a white solid.
