Versuchsvorschrift

A mixed solution comprising 14.5 g (0.1 mol) of 2,4-diamino-6-chloro-1,3,5-triazine synthesized in Reference Example 1 and 31.1 g (0.4 mol) of 40% aqueous solution of methylamine was heated under stirring and reacted finally at the reflux temperature thereof for 6 hours. After cooling the reacted solution, products were filtered off, and washed with cold water. The resulting filter residue was dried in vacuo at 70° C. for 6 hours to give 9.1 g (yield: 65%) of the titled compound. Malting point: 269° C.
