2-[3-(2-{2-[2-(tert-Butoxycarbonyl-methyl-amino)-ethoxy]-ethoxy}-ethoxy)-5-trifluoromethyl-phenyl]-8-[2-(4-tert-butoxycarbonyl-2-methyl-phenyl)-ethanesulfonyl]-4-oxo-1,3,8-triaza-spiro[4.5]dec-1-ene-3-carboxylic acid tert-butyl ester (37.4 mg, 39.7 μmol) was dissolved in 4 N hydrochloric acid-dioxane (0.79 mL). Water (14.3 μL, 795 μmol) was added and the mixture was stirred at room temperature for three hours. The reaction solution was concentrated under reduced pressure to give 3-methyl-4-{2-[2-(3-{2-[2-(2-methylamino-ethoxy)-ethoxy]-ethoxy}-5-trifluoromethyl-phenyl)-4-oxo-1,3,8-triaza-spiro[4.5]dec-1-ene-8-sulfonyl]-ethyl}-benzoic acid hydrochloride (28.0 mg, 98%).
