実験手順
To a stirred solution of {4-[2-(2,4-dichloro-phenoxy)-phenylsulfamoyl]-benzoylamino}-acetic acid ethyl ester (7.68 g, 14.67 mmol) in a mixture of tetrahydrofuran (36 mL), water (18 mL) and methanol (18 mL) lithium hydroxide monohydrate (3.09 g, 73.64 mmol) was added and the reaction mixture was stirred at room temperature for 2 h. The mixture was concentrated, the residue was dissolved in water, acidified with 1M hydrochloric acid, the precipitated solid was filtered off, washed with water and dried to yield 6.76 g (93%) of the title compound as a yellowish solid. MS (EI) 496.2 (MH+).
