Procedure

51 g. of 4-Chloro-1-ethyl-1H-pyrazolo[3,4-b]pyridine-5-methanol (0.24 mol.) and 300 ml. of n-butylamine are heated at 100° in an autoclave for seven hours. After cooling, the surplus butylamine is removed by distillation in vacuo and the residue is treated with a total amount of 200 ml. of ether. The etheral solution is evaporated, yielding 51.9 g (87%) of the alcohol, m.p. 60°-72°. Recrystallization with hexane provides the pure 4-butylamino-1-ethyl-1H-pyrazolo[3,4-b]pyridine-5-methanol, m.p. 85°-86°.
