Synthetic Route of 117007-52-0 , The common heterocyclic compound, 117007-52-0, name is 3-Iodo-1H-pyrazolo[3,4-b]pyridine, molecular formula is C6H4IN3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
General procedure: 3-Iodo-1H-indazole (S1, 5.00 g, 19.5 mmol) was placed in a round-bottom flask and dissolved in tetrahydrofuran (100 mL). 4-Dimethylaminopyridine (0.24 g, 1.9 mmol, 0.1 equiv) was then added, followed by di-tert-butyl dicarbonate (5.4 mL, 24 mmol, 1.2 equiv). Triethylamine (5.4 mL, 39 mmol, 2.0 equiv) was slowly added to the clear, brown solution by syringe. The resulting solution was stirred at room temperature until it was complete as determined by TLC. The reaction was then diluted with water (75 mL) and ethyl acetate (50 mL). After separating the layers, the aqueous phase was extracted with additional ethyl acetate (3 × 50 mL). The combined organic layers were washed with brine (100 mL), then shaken over magnesium sulfate, filtered, and concentrated under reduced pressure to give the crude product. This material was purified by column chromatography over silica gel (hexanes/ethyl acetate: 100/0 to 90/10) to give the title compound as an orange solid (6.20 g, 93%).
The synthetic route of 117007-52-0 has been constantly updated, and we look forward to future research findings.
