60-75% | With acetic acid; sodium nitrite; In water; | EXAMPLE 2 2,4,6-triamino-5-nitrosopyrimidine was prepared by dissolving 1.0 mole of <strong>[1004-38-2]2,4,6-triaminopyrimidine</strong> in 1040 ml of water and 1.5 moles of acetic acid, maintaining the temperature in the range of about 0-16 C. Then 1.0 mole of sodium nitrite was added to the reaction mixture while controlling the reaction temperature in the range of 0-20 C. To the final reaction mixture prepared above, sodium dithionite was added over a period of about 30 minutes to an hour while allowing the reaction mixture to reach 60 C. The reaction mixture was then filtered hot and the filtrate was cooled to 5 C. at which temperature the desired product crystallized from the filtrate and was separated, giving about a 60-75% yield of 2,4,5,6-tetraaminopyrimidine sulfite, which assayed about 95% pure by high pressure liquid chromatography. |
