Reaction Steps

To a solution of 3-fluoro-6-methyl-2-(2,3,5-trifluorophenyl)pyridine (1.0 equiv.) in water and t-BuOH (2:1, 0.06 M) was added potassium permanganate (10 equiv.) and the solution was heated at 90° C. for 5 hours. Upon cooling to room temperature, the solution was filtered, and the filtrate was concentrated under reduced pressure to yield 5-fluoro-6-(2,3,5-trifluorophenyl)picolinic acid in 89% yield. LC/MS=272.0 (M+H), Rt=0.80 min.
