Yield	Reaction Conditions	Operation in experiment
	With NaNO2; In water monomer; glacial acetic acid;	Step 1) Synthesis of 4,5,6-triamino-2-methylthiopyrimidine To a solution of 245g of <strong>[1005-39-6]4,6-diamino-2-methylthiopyrimidine</strong> dissolved in 800 ml of acetic acid was added 250 ml of water. The reaction solution was cooled to 10C and thereto was added a solution of 119g of NaNO2 dissolved in 250 ml of water while maintaining the temperature at 10C. The reaction mixture was stirred at room temperature for 2 hours, filtered and dried to obtain 4,6-diamino-5-nitroso-2-methylthiopyrimidine, which was then dissolved in 1l of water.
	With glacial acetic acid; NaNO2; In water monomer; at 20℃; for 1.0h;	To a solution of 2-1 (2g, 12.80mmol, 1eq) in H2O (20mL) and AcOH (7.35g, 122.40mmol, 7.00mL, 9.56eq) was slowly added NaNO2 (1.77g, 25.61mmol, 2eq), the reaction solution was stirred at 20 C for 1 hour, the reaction solution was filtered, and the filter cake was dried under high vacuum to obtain compound 2-a.
