The reactant was hydrogenated and stirred for 4 hr. The solution was filtered through silica gel-sand panel funnel. The filtrate was retained and the solvent was evaporated in vacuo. The resultant substance was purified by flash chromatography with silica gel column and eluated with chloroform:methanol=95:5 to give 2-(N-benzoyl)amino-5-aminopyrimidine (200 mg).
