Procedure

To a stirred solution of 223 g. of 1-(2-pyridyl)-ethanol in 1500 ml. of dry dimethylsulfoxide is added 2.3 moles of sodium hydride in portions, under nitrogen, maintaining the temperature of 20° C. After two hours, 331 g. of methyl iodide is added at 20° C. After stirring for another three hours, the mixture is poured onto ice-water and extracted three times with ether. The organic phase is washed with water, dried over magnesium sulfate, concentrated in vacuo, and the residue is distilled to give 2-(1-methoxyethyl)pyridine.
