Adding a certain compound to certain chemical reactions, such as: 118430-74-3, name is 3-Cyclopropyl-1-methyl-1H-pyrazol-5-amine, belongs to pyrazoles-derivatives compound, 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 118430-74-3, name: 3-Cyclopropyl-1-methyl-1H-pyrazol-5-amine
Synthesis of N-(3-cyclopropyl-1-methyl-1H-pyrazol-5-yl)-7-(3,5-dimethylisoxazol-4-yl)-6-methoxy-2-((methylsulfonyl)methyl)-9H-pyrimido[4,5-b]indol-4-amine (Cpd. No. 289) Pd2(dba)3 (18 mg) and BINAP (26 mg) were mixed in anhydrous toluene. And the mixture was heated at reflux for 3-4 minutes. This mixture was transferred into a round-bottom flask containing ZBB273 (60 mg), 3-cyclopropyl-1-methyl-1H-pyrazol-5-amine (84 mg), K3PO4 (130 mg), and toluene (4 mL). The mixture was heated at reflux for overnight before quenching with methanol. The reaction mixture was filtered and the mixture was purified by HPLC to yield Cpd. No. 289 as a CF3CO2H salt in 27 mg. ESI-MS calculated for C25H28N7O4S [M+H]+=522.19; Observed: 522.44.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 3-Cyclopropyl-1-methyl-1H-pyrazol-5-amine, and friends who are interested can also refer to it.
