Versuchsvorschrift
To 40 ml of methanol were added 7.60 g of the crude 2-benzylamino-3,5,6-trifluoropyridine as described above together with 0.55 g of 10% palladium on carbon and 2 ml 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. The precipitate was dispersed in n-hexane, and collected by filtration to obtain 3.85 g of the title compound as a colorless solid.
