Procedure

A mixed solution of 14.5 g (0.1 mol) of 2,4-diamino-6-chloro-1,3,5-triazine prepared in the (a), 100 mL of water and 29.2 g (0.4 mol) of butylamine was heated while stirring, followed by being finally reacted for 6 hours at reflux temperature. After cooling reaction liquid, a product was filtered, followed by washing with a large quantity of water and then with toluene. The product was dried at 70° C. in vacuo for 6 hours to obtain 17.5 g (a yield of 96%) of the above-identified compound. Melting point: 167° C.
