Versuchsvorschrift

4-Cyclohexylamino-1-ethyl-1H-pyrazolo[3,4-b]pyridine-5-carboxylic acid (0.200 gm, 0.0006 mole) (example 5) and N,O-dimethylhydroxylamine hydrochloride (0.102 gm, 0.0010 mole) were taken in dimethylformamide. At 0° C., hydroxybenzotriazole (0.162 gm, 0.0012 mole) and N-methylmorpholine (0.30 ml, 0.0027 mole) were added and the reaction mixture was stirred for about 1 h. 1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (0.266 gm, 0.0012 mole) was added and the reaction mixture was stirred for about 14 h. Water was added and extraction was carried out with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulphate and concentrated in vacuo. The compound was purified over preparative thin layer chromatography.
