Procedure

A solution of 4-allyl-2-(difluoromethoxy)benzonitrile (600 mg, 2.9 mmol) in 1:1 CH2Cl2/MeOH (15 mL) containing pyridine (0.5 mL, 6 mmol) was cooled to −78° C., and O3 was passed through until a blue color was present. N2 was then bubbled through to discharge the blue color and Me2S (5 ml) was added. The reaction mixture was allowed to warm and left overnight. The mixture was washed with 1 N HCl, aqueous NaHCO3, dried and concentrated to give crude 2-(difluoromethoxy)-4-(2-oxoethyl)benzonitrile.
