CO[C:3]1[N:8]=[C:7]([O:9][CH3:10])[N:6]=[C:5]([O:11][CH3:12])[N:4]=1.[NH3:13]>O>[NH2:13][C:3]1[N:4]=[C:5]([O:11][CH3:12])[N:6]=[C:7]([O:9][CH3:10])[N:8]=1A mixture of 10.1 g (0.059 mole) of 2,4,6-trimethoxy-1,3,5-triazine and water (100 mL) was stirred at 25° C. while 110 mL of 28% aqueous ammonia was added. The mixture was held at 48-51° C. for two hours before it was cooled to 25° C. and the insoluble white crystals were removed. The product was washed with water and dried to give 7.84 g (86%), mp 218-221° C. 1H NMR (DMSO-d): 3.81 (s, 6H); 7.38 (s, 2H). 13C NMR (DMSO-d6): 53.9, 169.0, 171.9.
