标题 :Process for the synthesis of diaminopyridine and related compounds
发明人：RITTER JOACHIM C
权利人:DU PONT; RITTER JOACHIM C
摘要:A process is provided for the synthesis of a diaminopyridine, such as 2,6-diaminopyridine and related compounds, which are used industrially as compounds and as components in the synthesis of a variety of useful materials. The synthesis proceeds by means of a chlorine-ammonia displacement in the presence of a copper source.
