A new synthetic route of 5-Bromo-1H-pyrazolo[3,4-c]pyridine

The synthetic route of 929617-35-6 has been constantly updated, and we look forward to future research findings.

Adding a certain compound to certain chemical reactions, such as: 929617-35-6, 5-Bromo-1H-pyrazolo[3,4-c]pyridine, 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, COA of Formula: C6H4BrN3, blongs to pyridine-derivatives compound. COA of Formula: C6H4BrN3

General procedure: To a stirred solution of 5-bromo-1W-pyrazolo[3,4-c]pyridine (1 g, 5.07 mmol) in DMF (10mL), 60% NaH (0.405 g, 10.14 mmol) was added at 0C and it was stirred at RT for 30 min. Then, (bromomethyl)cyclobutane (1.12 g, 7.56 mmol) was added to the mixture at 0 C and it was stirred at RT for 16 h. The reaction mixture was poured into ice water (50 mL) and extracted with EtOAc (2 x 30 mL). The combined organic layers were washed with brine (20 ml). The combined organic layers were dried over anhydrous Na2SO4, filtered and the filtrate was concentrated under reduced pressure. The crude compound was purified by column chromatography using 10% EtOAc/pet ether as eluent to afford fraction-1 5-bromo-1-(cyclobutylmethyl)-1H-pyrazolo[3,4-c]pyridine (reference example 6) (500 mg) as an off-white solid, and 20% EtOAc/pet ether as eluent to afford fraction-2 5- bromo-2-(cyclobutylmethyl)-2W-pyrazolo[3,4-c]pyridine (reference example 7) (450 mg) as an off-white solid Reference example 6: LC-MS (method 1): Rt = 2.30 min; m/z = 265.86 (M+H+). Reference example 7: LC-MS (method 1): Rt = 2.06 min; m/z = 265.61 (M+H+).

The synthetic route of 929617-35-6 has been constantly updated, and we look forward to future research findings.
