New downstream synthetic route of 5-(2-Ethoxyphenyl)-1-methyl-3-propyl-1H-pyrazolo[4,3-d]pyrimidin-7(6H)-one

The synthetic route of 139756-21-1 has been constantly updated, and we look forward to future research findings.

Adding a certain compound to certain chemical reactions, such as: 139756-21-1, 5-(2-Ethoxyphenyl)-1-methyl-3-propyl-1H-pyrazolo[4,3-d]pyrimidin-7(6H)-one, 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, HPLC of Formula: C17H20N4O2, blongs to pyrimidines compound. HPLC of Formula: C17H20N4O2

I-09a (2.5 g, 8.0 mmol) was added into CISO3H (R-05, 10 mL) at ice-water and stirred at r.t. for 2 hours. The reaction mixture was quenched by adding water, and then filtrated. The filtrate cake was collected and dried under vacuo to give I-i Oa (2.0 g) ESI-MS (Mi-i): 411 calc. for C17H19C1N404S: 410.1.

The synthetic route of 139756-21-1 has been constantly updated, and we look forward to future research findings.
