On December 27, 2011, Minter, Aaron; Stokes, Berlin published a patent.Quality Control of 3-Methylpyridine-2,6-diamine The title of the patent was Process for the synthesis of diaminopyridines from glutarimidines. And the patent contained the following:
A liquid-phase process is provided for the synthesis from glutarimidines of diaminopyridines 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 dehydrogenative aromatization process. The experimental process involved the reaction of 3-Methylpyridine-2,6-diamine(cas: 51566-22-4).Quality Control of 3-Methylpyridine-2,6-diamine
