Abstract

1391244 3 - Amino -1 H - pyrazolo pyridines HOECHST AG 29 June 1973 [30 June 1972] 31207/73 Heading C2C Novel 3-amino-1H-pyrazolopyridines of the formula wherein X is a primary, secondary or tertiary amino group, a hydrazino, hydroxylamino, ether or thioether group; Y is a hydrogen atom or an optionally substituted alkyl, cycloalkyl, aryl or heterocyclic radical, and Z is a hydrogen atom or an alkyl group, are prepared by reacting a 2,6-dihalogeno-3-cyanopyridine of the formula wherein Hal is chlorine or bromine, with ammonia, a primary or secondary amine, hydrazine, hydroxylamine, or a hydroxy or thio compound, and condensing the resulting compound of the formula with a hydrazine of the formula The reaction of the 2,6-dihalogeno-3-cyanopyridine is preferably carried out at a temperature of from 20‹ to 100‹ C. in an inert solvent, e.g. an aliphatic alcohol, and the condensation reaction is preferably carried out at a temperature of from 70‹ to 150‹ C. in an aqueous or aqueous-alcoholic solution.
