2-Methyl-6-nitropyridine

General procedure: Into a 2 dram vial was placed 5-nitro-8-hydroxyquinonline (63 mg, 0.33 mmol), Ru/PS nanoparticle catalyst (8.0 mg, 0.477 mmol Ru/gram catalyst, 1.2 mol%), and hydrazine monohydrate (42 muL, 2.5 equiv) in 4 ml of THF. The reaction mixture was stirred for 2 hr, at which point the solvent was removed under reduced pressure. The product was extracted from the solid mixture with 3x 2 ml EtOH. The combined ethanol extracts were then passed through a short silica plug in a pipet and the silica plug was washed 2 times with 1 ml ethanol. The EtOH was then removed on a rotary evaporator under reduced pressure. The product 5-(hydroxyamino)quinolin-8-ol was isolated as an orange solid (51 mg, 0.29 mmol, 87% yield). For some of the more complex substrates, the reaction results are highly temperature sensitive, the reactions can be forced to completion by adding extra equivalents of hydrazine, and by raising the temperature to 27 C.
