[Uses]

2-Methyl-3-nitropyridine is used as a starting reagent to synthesize 3-substituted-4 or 6-azaindoles, and is also used as a reagent to prepare 3-azaindolyl-4-arylmalemides (compounds that exhibit antiproliferative activity).
[Reactions]

2-Methyl-3-nitropyridine could be used to synthesize dichloro-(3-nitro-2-pyridyl)methylphosphonic dichloride. The chlorination of 2-methyl-3-nitropyridine using a mixture of PCl5 in POCl3[1].

[Synthesis]

Suzuki Reaction. A mixture of 2-chloro-3-nitro-pyridine 1 (793 mg, 5 mmol), methylboronic acid (329 mg, 5.5 mmol), Pd(PPh3) 4 (578 mg, 0.5 mmol) and K2CO 3 (2.073 g, 15 retool) in dioxane (25 mL) was refluxed for 2 days, then cooled to room temperature and filtered. The solvent was removed and the residue was isolated by chromatography (hexanes-EtOAc = 1:1) to provide 623 mg (90%) of 2-methyl-3-nitropyridine[2].
