Versuchsvorschrift
A solution of 2-methoxy-3-nitro-5-ethyl-6-methylpyridine (535 mg, 2.72 mmol) in methanol (8 mL) and tetrahydrofuran (8 mL) containing 5% palladium on carbon (83 mg) was hydrogenated at atmospheric pressure for 5 hours. The catalyst was filtered off the solvent evaporated to yield 436 mg (98%) of oily product.
