Procedure

To a solution of methyl 6-(2,6-difluoro-4-(hydroxymethyl)phenyl)-5-fluoropicolinate (1.0 equiv.) in DMF (0.20 M) (colorless) at 0° C. was added sodium hydride (1.2 equiv.) and the reaction was stirred at 0° C. for 2 min. Ethyl iodide (1.2 equiv.) was added and the reaction was allowed to warm to room temperature. After 1 h, additional 1.0 equiv. of NaH was added and stirred for 15 ml. Reaction was quenched by the addition of sat. Ammonium chloride. The aqueous was acidified with conc HCl to pH3 and extracted with ethyl acetate three times. The organics were combined, dried with MgSO4, filtered and concentrated. The crude mixture was used as is. LC/MS=326.0 (MH+), Rt=0.94 min.
