Procedure

To 4 ml of methanol were added all amount of the crude 2-benzylamino-3,5,6-trifluoro-4-methylpyridine as described above together with 0.18 g of 10% palladium on carbon and 2 ml of acetic acid, and the mixture was hydrogenated at 50° C. for one day. The catalyst was separated by filtration, and the solvent and the like were distilled off under reduced pressure to obtain 1.35 g of the title compound as a colorless solid.
