Procedure

To a stirred solution of 11.8 g. (0.1 mole) of 2-pyridylacetonitrile in dry dimethylsulfoxide at 10° C. is added 0.1 mole of sodium hydride (dispersed in mineral oil). After 20 minutes, 0.1 mole of chloromethyl methyl ether is added with cooling and the mixture is kept at 10° C. for 2 hours, then allowed to warm to room temperature overnight. The reaction mixture is poured into water and extracted with ether. The organic phase is washed with water, dried over anhydrous sodium sulfate, concentrated under vacuum and distilled to give 3-methoxy-2-(2-pyridyl)propionitrile.
