Versuchsvorschrift
4-{2-[(3-Dimethylaminomethylbenzofuran-2-carbonyl)amino]ethoxy}benzoic acid methyl ester (70.0 g, 0.177 mol) was suspended in methanol (350 ml). 50% Potassium hydroxide (139.8 g, 1.062 mol) was added and the reaction mixture was heated to 60° C. until completion of reaction. After cooling to room temperature, the resulting crystals were filtered on a coarse frit and washed with methanol. The crystals were dried in vacuo to give 4-{2-[(3-dimethylaminomethylbenzofuran-2-carbonyl)amino]ethoxy}benzoic acid potassium salt (72.0 g) as a white solid.
