Adding a certain compound to certain chemical reactions, such as: 49721-45-1, Pyrimidine-4,5,6-triamine sulfate, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Computed Properties of C4H9N5O4S, blongs to pyrimidines compound. Computed Properties of C4H9N5O4S
EXAMPLE 2 4-Amino-7-(3-chlorophenyl)pteridine To a suspension of 5.2 g. of selenous acid in 40 ml. of dioxane was added 3.09 g. of m-chloroacetophenone. The mixture was refluxed for 4 hours, filtered and the filtrate was evaporated to dryness. A hot suspension of 3.90 g. of this glyoxal in 15 ml. of ethanol was added to a stirred suspension of 3.26 g. of 4,5,6-triaminopyrimidine sulfate and the condensation product was worked up as in Example 1 to produce 1.6 g. of 4-amino-7-(3-chlorophenyl)pteridine, melting at 260-4 degrees C. This compound was tested at 100 mg/kg by the procedure of Example 1, giving the excretion rates shown in Table I.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,49721-45-1, Pyrimidine-4,5,6-triamine sulfate, and friends who are interested can also refer to it.
