実験手順
4 M hydrochloric acid-dioxane (1.80 ml) and water (0.0173 ml, 0.960 mmol) were added to 8-[2-(4-tert-butoxycarbonyl-2-methyl-phenyl)-ethanesulfonyl]-2-(3-but-3-ynyloxy-5-trifluoromethyl-phenyl)-4-oxo-1,3,8-triaza-spiro[4.5]dec-1-ene-3-carboxylic acid tert-butyl ester (35.9 mg, 0.048 mmol), and the mixture was stirred at room temperature for five hours. The reaction solution was concentrated under reduced pressure to give 4-{2-[2-(3-but-3-ynyloxy-5-trifluoromethyl-phenyl)-4-oxo-1,3,8-triaza-spiro[4.5]dec-1-ene-8-sulfonyl]-ethyl}-3-methyl-benzoic acid as a white solid.
