Versuchsvorschrift
To a stirred solution of ethyl 3-{[1-methyl-5-(tritylamino)-1H-pyrazol-4-yl]amino}-3-oxopropanoate (1.3 g) in tetrahydrofuran (30 ml) was added 1N aqueous sodium hydroxide solution (3.1 ml), and the mixture was stirred at room temperature for 3 hours. Tetrahydrofuran was removed in vacuo and the residue was made acidic with diluted citric acid. The resulting precipitate was collected by filtration and dried under reduced pressure to give 3-{[1-methyl-5-(tritylamino)-1H-pyrazol-4-yl]amino}-3-oxopropanoic acid (1.22 g).
