Reaction Steps

A mixture of ethyl 2-hydroxy-pyridine-4-carboxylate (1.0 g, 6 mmol), (Chem. Abs. 1957, 8740c), methyl iodide (1 ml) and silver(I)carbonate (1.64 g) in toluene (20 ml) was heated at reflux for 2 hours. The mixture was allowed to cool and the insolubles removed by filtration through diatomaceous earth and the pad was washed through with ethyl acetate. The filtrate was washed with water, dried (MgSO4) and the solvent removed by evaporation to give ethyl 2-methoxy-pyridine-4-carboxylate (0.93 g, 86%) as a yellow oil.
