Reaction Steps
To a solution of methyl 6-(2,6-difluoro-3-methylphenyl)picolinate (1.0 equiv.) in THF was added sodium hydroxide (10 equiv.) and the reaction was stirred for 2 hours. The solution was diluted with ethyl acetate and washed with 1N NaOH (2×). The combined basic aqueous washes were combined and acidified with concentrated HCl. The acidic aqueous phase was extracted with ethyl acetate (2×), the combined organic layers were dried with magnesium sulfate, filtered, and concentrated in vacuo to provide 6-(2,6-difluoro-3-methylphenyl)picolinic acid as a white solid in 85% yield. LC/MS=250.0 (M+H), Rt=0.76 min.
