86% With ammonia In water at 25 - 51℃; for 2 h; Example 3A
Preparation of 2-amino-4,6-dimethoxy-1,3,5-triazine precursor
A 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 28percent 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 (86percent), 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.

YieldReaction ConditionsOperation in experiment
85.4% With ammonia; sodium methylate In methanol; water; toluene EXAMPLE 2
There is added to the atmosphere above the reaction mixture 5.1 g (0.299 moles) of ammonia gas over a 25 minute period at 20° to 40° C., to a mixture of 26.8 g (0.145 moles) of cyanuric chloride and 100 g of toluene.
The mixture is cooled to 10° C. and 25 g of methanol is added.
There is then added over a five minute period, 99.0 g of a 25percent solution of sodium methoxide to the resulting mixture causing it to reflux.
The mixture is kept under reflux for 15 minutes; there is then added 100 g of water.
A white solid is obtained after the mixture is filtered and washed with 50 g of water.
After drying at 80° C. for several hours, 20.3 g of a white solid is obtained.
Based on method of preparation, there is obtained an 85.4percent yield of 2-amino-4,6-dimethoxy-1,3,5-triazine (ADMT) based on cyanuric chloride.
