Reaction Steps

490 mg of 2,6-dichloro-N-methoxy-N-methyl isonicotinamide was dissolved in tetrahydrofuran, 2.1 ml of 3M methyl magnesium bromide tetrahydrofuran solution was added dropwise at 0° C., and the mixture was stirred at 0° C. for 1 hour. To the reaction solution was added ammonium chloride aqueous solution, and the mixture was diluted with ethyl acetate. The mixture was washed with brine, and then dried over magnesium sulfate. The solvent was distilled off under reduced pressure to obtain 325 mg of the objective compound.
