Versuchsvorschrift

Hydroxylamine hydrochloride (0.255 gm, 0.0036 mole) and sodium acetate (0.301 gm, 0.0036 mole) were added to a stirred solution of 4-(cyclohexylamino)-1-ethyl-1H-pyrazolo[3,4-b]pyridine-5-carbaldehyde (0.250 gm, 0.0009 mole) (example 7) in ethanol. The reaction mixture was allowed to stir at room temperature for about 2 h. Ethanol was removed under reduced pressure and residue was poured in water. The title compound was then filtered and washed with water twice and finally with hexane.
