Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 330786-24-8, name is 3-(4-Phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine. This compound has unique chemical properties. The synthetic route is as follows.
Under nitrogen protection, 20 g of triphenylphosphine supported by nano-Fe3O4 was added to the three-necked flask (particle diameter 100 nm,PPh3 loading 1 mmol/g), adding intermediate (II) (3.04 g, 10 mmol),N-Boc-3S-hydroxypiperidine (III) (2.02 g, 10 mmol), diethyl azodicarboxylate (3.67 g, 21.1 mol)And 1,4-dioxane (100 mL), the reaction was stirred at 20 C until the intermediate (II) was consumed completely, and the reaction was stopped.The external magnet adsorbs the magnetic nano-load, and the reaction solution is decanted, and the nanoparticles are washed with 1,4-dioxane (50 mL¡Á2).The washing liquid and the reaction liquid were combined, concentrated under reduced pressure to (20 mL), and then added to 10 mol/L hydrochloric acid (40 mL), and the mixture was completely removed.Dichloromethane (50 mL x 3) was extracted and the aqueous phase was neutralized with saturated sodium carbonate to pH >Filtration and vacuum drying to obtain a solid intermediate (IV) (3.30 g, yield: 85.3%).No residual phenoxide was detected.
According to the analysis of related databases, 330786-24-8, the application of this compound in the production field has become more and more popular.
