Synthesis of the mutagenic 2-amino-1,6-dimethylimidazo[4,5-b]pyridine (1,6-DMIP) and five of its isomers was written by Lindstroem, Stefan;Ahmad, Tania;Grivas, Spiros. And the article was included in Heterocycles in 1994.Formula: C6H6N2O3 This article mentions the following:
Synthetic routes to 2-amino-1,6(1,5-, 1,7)-dimethylimidazo[4,5-b]pyridine I (R = Me), and its 3,5-, 3,6- and 3,7-di-Me isomers II (R = Me) from Me derivatives of 3-hydroxy- or 2-aminopyridine and 2-chloronicotinic acid are described. In the experiment, the researchers used many compounds, for example, 3-Hydroxy-6-methyl-2-nitropyridine (cas: 15128-90-2Formula: C6H6N2O3).
3-Hydroxy-6-methyl-2-nitropyridine (cas: 15128-90-2) belongs to pyridine derivatives. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Formula: C6H6N2O3
