N 1,N 1-Disubstituted N 2-(2-nitrophenyl)- and N 2-(2-nitropyridyl)-phenylacetamidines, derived from the thermal rearrangement of 5-amino-4, 5-dihydro-1-(2-nitroaryl)-4-phenyl-1H-1,2,3-triazoles, are obtained in a one-pot reaction from phenylacetaldehyde, a secondary amine and an aryl azide and undergo ring closure to the title compounds on reaction with sodium ethoxide in ethanol.
N 1,N 1-二取代的 N 2-(2-硝基苯基)- 和 N 2-(2-硝基吡啶基)-苯基乙脒,衍生自 5-氨基-4, 5-二氢-1-(2-硝基芳基)的热重排)-4-苯基-1H-1,2,3-三唑,由苯乙醛、仲胺和芳基叠氮化物通过一锅反应获得,并在乙醇中与乙醇钠反应,闭环得到标题化合物。
