  Although aminopyridines are primaryamines,achieved mixture aren抰 composed of three ureas of almost equal proportionincluding symmetric dipyridylureas,just giving priority to unsymmetrical ureas. Theyield of the products is from middle to fine.

  氨基吡啶虽为一级胺，但并未得到含对称的二吡啶脲的三种比例相当的脲的混合物，而是以非对称取代的吡啶脲为主要产物，产率从中等到良好。
