The resulting solution is stirred under N2 for 45 min. Solid methyl(4,6-dimethoxy-1,3,5-triazin-2-yl)carbamate (1.1 g) is added and the mixture is heated at reflux for 60 h. The reaction is quenched sequentially with acetic acid (1 ml), 6 N HCl (2.5 ml) and water (13 ml). The organic solution is retained, dried with MgSO4, and is concentrated to an oil-solid mixture. Filtration afforded 0.6 g yellow solid m.p. 169°-191° C. (dec). The infrared spectrum showed characteristic absorption bands at 3300 and 1700 cm-1.
