Procedure
14 g. of well pulverized 1-ethyl-4-hydrazino-1H-pyrazolo[3,4-b]pyridine-5-carboxamide (0.0635 mol.) are dissolved in 500ml. of anhydrous acetone and the solution is allowed to stand overnight. Then excess acetone is removed in vacuo and the residual 1-ethyl-4-[2-(1-methylethylidene)hydrazino]-1H-pyrazolo[3,4-b]pyridine-5-carboxamide is recrystallized from ethyl acetate, m.p. 217°-218°, yield 9.75 g. (59%).
