2，6－二苦胺基－3，5－二硝基吡啶的新法合成探讨

A NEW METHOD OF SYNTHESIZING 2,6-BIS(PICRYLAMINO)-3,5-DINITROPYRIDINE

本文采用两步缩合，先以二硝基氯苯（代替苦基氯）与２，６－二氨基吡啶反应得到Ｎ－（２，４－二硝基苯基）－２，６－二氨基吡啶（２），（２）再与苦基氯缩合得到Ｎ－（２，４－二硝基苯基）－Ｎ＇－苦基－２，６－二氨基吡啶（３），将（３）硝化就得到题称化合物（４）。

This paper reports a new method of synthesizing 2,6-bis(picrylamino)-3,5-dinitropyridine by condensation reaction of 2,6-diaminopyridine and 2,4-dinitro-chlorobenzene the condensation product was then reacted with picrylchloride and getN-(2,4-dinitrophenyl)-N '-picry1-2,6-diaminopyridine(3) which was nitrated and ob-tained the titled compound(4).
