Procedure
Compound No. 2, FIG. 1A: A suspension of Compound No. 11 (2-amino-4-(3,5-diacetylphenyl)amino-6-methylpyrimidine) (0.284 g), was suspended in 1:1 acetonitrile-tetrahydrofuran was treated with methyl iodide (2 mL) and heated at 40°-45° C. under a reflux condenser for 18 hr. Cooling and filtration gave 0.35 g of 2-amino-4-(3,5-diacetylphenyl)amino-1,6-dimethylpyrimidinium iodide (Compound No. 2), mp 292° C.
