2-chloro4-methyl-6-phenyl-nicotinonitrile (455 mg, 1.99 mmol) was dissolved in 20 mL of DME, added with 95% sodium methoxide (1.13 g, 19.90 mmol) and then stirred at room temperature for about 1 hour. The mixture was added to cool water and was adjusted to have a pH of about 6 to 7 with 10% HCl and then extracted with ethyl acetate. A silica gel column chromatography (10% EtOAc/Hexane) was performed on the resulting residue and 370 mg (83%) of 2-methoxy-4-methyl-6-phenyl-nicotinonitrile was obtained in white solid.
