Procedure
Under a nitrogen atmosphere, to a solution of 2-(hydroxymethyl)isonicotinonitrile (5.08 g) and N-ethyldiisopropylamine (26.5 mL) in DMF (76 mL) was added chloromethyl methyl ether (8.63 mL) at room temperature, and the mixture was stirred at room temperature for 20 min. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (1.87 g) as an orange oil.
