Synthetic Route of 1083181-26-3 , The common heterocyclic compound, 1083181-26-3, name is 3-Iodo-1H-pyrrolo[3,2-b]pyridine, molecular formula is C7H5IN2, 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.

Sodium hydride (140 mg, 60% dispersion in mineral oil) was added to a solution of 3-iodo-1H-pyrrolo[3,2-b]pyridine (Intermediate 1), (700 mg) in dimethyl acetamide (7 mL) at 0 C. The RM was allowed to warm to rt and was stirred for 30 min. To which, was added 4-fluoro-4′-methyl-1,1′-biphenyl (Intermediate 71), (840 mg) and the reaction mixture stirred for a further 1 h. The reaction was quenched with water (20 mL) and extracted with EtOAc (3*20 mL). The organic phases were combined, dried (Na2SO4), filtered, and evaporated under vacuum. The crude product was purified by column chromatography (silica), eluting with 20:80 EtOAc/hexanes to afford the title compound (700 mg). LCMS: m/z 429.04 [M+H]+. 1H NMR (400 MHz, DMSO-d6) ppm 5.51 (s, 2H), 7.21 (dd, J=8.2, 4.6 Hz, 1H), 7.23-7.30 (m, 2H), 7.35 (d, J=8.2 Hz, 2H), 7.54-7.62 (m, 2H), 7.62-7.69 (m, 2H), 8.00 (dd, J=8.2, 1.2 Hz, 1H), 8.09 (s, 1H), 8.40 (dd, J=4.4, 1.4 Hz, 1H)

The synthetic route of 1083181-26-3 has been constantly updated, and we look forward to future research findings.

Application of 1083181-26-3, 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.1083181-26-3, name is 3-Iodo-1H-pyrrolo[3,2-b]pyridine, molecular formula is C7H5IN2, molecular weight is 244.03, as common compound, the synthetic route is as follows.

To a mixture of 3-iodo-1H-pyrrolo[3,2-b]pyridine (Intermediate 1), (350 mg) and potassium carbonate (791 mg) in DMF (8 mL) stirred at 0 C. under nitrogen was added 2-(4-(bromomethyl)-3-fluorophenyl)-6-methylpyridine hydrobromide (Intermediate 65), (620 mg). The reaction mixture was allowed to warm to rt and was stirred overnight. Water (50 mL) was added to the reaction mixture and the reaction mixture was extracted with EtOAc (100 mL). The organic phase was washed with brine (75 mL), dried (Na2SO4), filtered and evaporated under vacuum. The crude product was purified by column chromatography (silica) eluting with 28:72 EtOAc:hexanes to afford the title compound (580 mg) which was taken on as such. LCMS: m/z 444.11 [M+H]+.

The chemical industry reduces the impact on the environment during synthesis 1083181-26-3, I believe this compound will play a more active role in future production and life.
