Reaction Steps

3,5-Dioxo-4-sodio-2,3,4,5-tetrahydro-1,2,4-triazine monohydrate (770 mg) dissolved in water (60 ml) is hydrogenated for 4 hours in the presence of platinum oxide (100 mg) at atmospheric pressure. The catalyst is filtered off, and the filtrate is concentrated in vacuo to give a colorless transparent liquid. The liquid is dissolved in ethanol (30 ml), and the solvent is then removed in vacuo to give amorphous solids of 3,5-dioxo-4-sodio-hexahydro-1,2,4-triazine dihydrate (Compound No. 4). Yield, 850 mg (98.2%). Softening temperature, 122.3° C.
