1.2. Synthesis of 2-amino-4,6-dimethoxy-5-nitrosopyrimidine 34.8 g (0.297 mol) of isopentyl nitrite was added to a solution of 41.9 g (0.270 mol) 2-amino-4,6-dimethoxypyrimidine in 675 mL dimethylsulfoxide and stirred for 96 hours at room temperature. After the reaction was complete, the deep blue solution was poured into 2.5 L water and stirred for 1 hour at room temperature. The resulting precipitate was filtered off and washed with water. After drying, 2-amino-4,6-dimethoxy-5-nitrosopyrimidine (32.8 g, 66%) was obtained as a light blue solid. Mp.: 215-218 C. (decomposition) 1H NMR (300 MHz, d6-DMSO): delta=3.94 (s, 6H, 4-OMe, 6-OMe), 8.28 (s, 2H, NH2). 13C NMR (125 MHz, d6-DMSO): delta=54.9 (4-OMe, 6-OMe), 141.9 (5-C), 163.3 (6-C, 4-C), 173-0 (2-C)
