To 800 mg of trifluoroacetic acid was added 340 mg of 2-t-butylamino-3-fluoro-5-methyl-6-(1,1,3,3-tetramethylbutylamino)pyridine, and the mixture was allowed to stand at room temperature for 30 minutes. The solution was concentrated under reduced pressure to obtain crude 2,6-diamino-3-fluoro-5-methylpyridine as a pale brown solid residue.
