4,6-dimethyl-2-chloro-nicotinonitrile (600 mg, 3.60 mmol) was dissolved in 30 mL of anhydrous THF and then added with sodium phenoxide trihydrate (3.06 g, 18.00 mmol) and stirred at 80° C. overnight. The mixture was extracted with methylene chloride, dried with anhydrous sodium sulfate, filtered and then concentrated under reduced pressure. A silica gel column chromatography (10% EtOAc/Hexane) was performed on the resulting residue and 730 mg (90%) of 4,6-dimethyl-2-phenoxy-nicotinonitrile was obtained in white solid.
