Procedure

34.7 g. of 5-benzoyl-4-ethoxy-1-(2-furanyl)methyl-1H-pyrazolo[3,4-b]pyridine (0.1 mol.) is refluxed for 10 hours with 50 ml. of sec. butylamine. The excess amine is removed in vacuo and the residue recrystallized from methanol to obtain 5-benzoyl-4-sec.butylamino-1-(2-furanyl)methyl-1H-pyrazolo[3,4-b]pyridine, yield 31 g. (83%), m.p. 112°-114° (methanol).
