A suspension of 2-methoxy-3-(2-nitroethenyl)-5-ethyl-6-methylpyridine (445 mg, 2.0 mmol) in methanol (10 mL) and 4.7M methanolic hydrogen chloride (2 mL) containing 5% palladium/carbon (110 mg) was hydrogenated at atmospheric pressure over 10-20 hours. The catalyst was filtered off and the solvent evaporated. The residue was made basic with sodium hydroxide solution and the product extracted into methylene chloride, dried, filtered and the solvent evaporated to yield 332 mg of crude oily product. No further purification was performed.
