Abstract

The novel compound <FORM:1115607/C2/1> is prepared by hydrogenation, in the presence of a hydrogenation catalyst, of 4,41-diamino-5,51-dinitro -2,21-dipyridyl. Intermediates isolated are 4,41-dinitramino-2,21-dipyridyl from nitration of 4,41-diamino-2,21-dipyridyl, and 4,41-diamino - 5,51 - dinitro - 2,21 - dipyridyl by rearrangement of 4,41-dinitramino-2,21-dipyridyl under heat.
