This compound has unique chemical properties. The synthetic route is as follows. HPLC of Formula: C8H8ClNO2
A mixture of methyl 2-chloro-6-methyl-pyridine-4-carboxylate (1.8 g, 10 mmol) and 10% palladium-on-charcoal catalyst (200 mg) in methanol (100 ml) was stirred under hydrogen at 5 atmospheres pressure. The catalyst was removed by filtration and the volatiles removed from the filtrate by evaporation. The residue was treated with 10% aqueous sodium hydroxide solution and extracted with ether (3*30 ml). The combined extracts were dried (MgSO4) and the solvent removed by evaporation to give methyl 2-methyl-pyridine-4-carboxylate (800 mg, 53%) as an oil.
