Electric Literature of 866546-09-0, The major producers of chemicals have been the Europe, Japan and China. 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 866546-09-0, name is 3-Bromo-5-chloro-1H-pyrrolo[2,3-b]pyridine. This compound has unique chemical properties. The synthetic route is as follows.

To a stirred suspension of 60% sodium hydride (5.7 g, 143 mmol) was added 3-bromo-5- chloro 1H pyrrolo[2,3-b]pyridine (2) (30 g, 130 mmol) in DMF (200 mL) at 0 C. After 1h, a solution of 4-toluenesulfonyl chloride (37.17 g, 195 mmol) in DMF (100 mL) was added slowly at the same temperature and stirred for 2 h. After completion of the reaction (as indicated by TLC), the mixture was poured in to cold water (500 mL), filtered the precipitated solid and dried under reduced pressure to afford 3-bromo-5-chloro-1-tosyl-1H-pyrrolo[2,3-b]pyridine (3) (40 g, 103 mmol, 80% yield) as an off- white solid. TLC system: 10% EtOAc in hexane Rf : 0.8 LCMS (ESI): m/z 386.4 [M+H]+

While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 866546-09-0, 3-Bromo-5-chloro-1H-pyrrolo[2,3-b]pyridine.
