New downstream synthetic route of 151266-23-8

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,151266-23-8, its application will become more common.

Application of 151266-23-8, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 151266-23-8, name is 3-Iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine. A new synthetic method of this compound is introduced below.

Compound 2-4 is synthesized as shown in Scheme 2. Compound 1-3 is reacted with isopropyl bromide in dimethylformamide with potassium carbonate at 80 C., to provide the 1-isopropyl pyrazolopyrimidine intermediate, compound 2-1. This intermediate with the protected indolyl boronic acid species 2-2, using tetrakistriphenylphosphine palladium catalysis in DME-water solvent at 80 C. for 4-5 hours, to produce the Suzuki coupling product, compound 2-3. Removal of the protecting groups with acid in dioxane yields the product, 2-(4-amino-1H-pyrazolo[3,4-d]pyrimidin-3-yl) iodide (Cpd. 2-4).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,151266-23-8, its application will become more common.
