9/23/21 News A new synthetic route of 139756-22-2

At the same time, in my other blogs, there are other synthetic methods of this type of compound,139756-22-2, 4-Ethoxy-3-(1-methyl-7-oxo-3-propyl-6,7-dihydro-1H-pyrazolo[4,3-d]pyrimidin-5-yl)benzene-1-sulfonyl chloride, and friends who are interested can also refer to it.

Adding a certain compound to certain chemical reactions, such as: 139756-22-2, 4-Ethoxy-3-(1-methyl-7-oxo-3-propyl-6,7-dihydro-1H-pyrazolo[4,3-d]pyrimidin-5-yl)benzene-1-sulfonyl chloride, 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, Formula: C17H19ClN4O4S, blongs to pyrimidines compound. Formula: C17H19ClN4O4S

Using the procedure described in Example 1, the reaction solvent and proton scavenger were varied.
