Category: 1187830-47-2

Related Products of 1187830-47-2, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.1187830-47-2, name is 4,5,6,7-Tetrahydro-2H-pyrazolo[4,3-b]pyridine hydrochloride, molecular formula is C6H10ClN3, molecular weight is 159.62, as common compound, the synthetic route is as follows.

a) 4,5,6,7-Tetrahydro-2H-pyrazolo[4,3-b]pyridine.HCl (319 mg, 2 mmol) was combined with Boc2O (480 mg, 2.2 mmol) and K2CO3 (1.3 mL, 3 M aqueous, 2 equiv) in CH2Cl2 (10 mL). After 15 hours, the starting amine was consumed (LCMS). The reaction slurry was washed with brine and the organic layer was dried on MgSO4, filtered, and concentrated to give a viscous yellow oil (446 mg, 96%) that was used without further purification. MS: (ES) m/z calculated for C11H18N3O2 [M+H]+ 224.1, found 224.2.

Statistics shows that 1187830-47-2 is playing an increasingly important role. we look forward to future research findings about 4,5,6,7-Tetrahydro-2H-pyrazolo[4,3-b]pyridine hydrochloride.

Adding a certain compound to certain chemical reactions, such as: 1187830-47-2, 4,5,6,7-Tetrahydro-2H-pyrazolo[4,3-b]pyridine hydrochloride, 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, Formula: C6H10ClN3, blongs to pyridine-derivatives compound. Formula: C6H10ClN3

To a mixture of 4,5,6,7-tetrahydro-2H-pyrazolo[4,3-b]pyridine (500 mg, 3.13 mmol, HCl, CAS1187830-47-2) and (Boc)2O (752 mg, 3.45 mmol) in MeOH (15 mL) was added aq.K2CO3 (3 M, 2.09 mL). The reaction mixture was stirred at 20 C. for 15 hours. On completion, the mixture was concentrated in vacuo. The residue was purified by silica gel chromatography (SiO2) to give the title compound (500 mg, 71% yield) as a white solid. 1H NMR (400 MHz, DMSO-d6) delta 12.05 (s, 1H), 7.55 (s, 1H), 3.66-3.55 (m, 2H), 2.65 (t, J=6.4 Hz, 2H), 1.94-1.82 (m, 2H), 1.51 (s, 9H).

The synthetic route of 1187830-47-2 has been constantly updated, and we look forward to future research findings.
