Reaction Steps
To 0.87 g (6 mmol) of 4-chloro-5-fluoro-2-picoline, the product of Example 66, in 20 mL of chloroform cooled to -45° C., is added 0.75 mL of t-butylhypochlorite. The reaction mixture is stirred at -45° C. for 2 hours and at 0° C. for 2 hours. The reaction mixture is then poured into water and the resultant aqueous mixture is extracted with methylene chloride. The organic solution is dried over anhydrous magnesium sulfate, filtered, concentrated under reduced pressure and distilled to afford the title compound.
