실험 절차

22.8 g (0.1 mol) of 1-methyl-3-isopropylideneamino-4-methylmercapto-tetrahydro-1,3,5-triazine-2,6-dione (prepared according to Example C-1) were dissolved in 250 ml of ethanol and warmed, with addition of a little p-toluene-sulphonic acid, for 5 hours to 50°C, a vacuum of approximately 200 mm Hg being applied. The mixture was evaporated in vacuo and the residue was recrystallized from ethanol. 18 g (96%) of 1-methyl-3-amino-4-methylmercapto-tetrahydro-1,3,5-triazine-2,6-dione were obtained as colorless needles, melting point 174°-175°C.
