Procedure

A mixture of 3.00 grams (0.0148 mols) of 2,4-diamino-6-(di-2-propenylamino)-1,3,5-triazine-3-oxide and 4.50 grams of pyridine sulfur trioxide in 3 ml of DMF is stirred for 2 hr. Water (240 ml) is added and the mixture is warmed on a steam bath for 4 min. The white crystals are filtered and dried to yield 3.20 grams of the titled product, a 71% yield. The crystals are homogeneous by TLC. A sample recrystallized from methanol-water decomposes at 258° C.
