Analyzing the synthesis route of 6-Bromo-1H-pyrrolo[3,2-b]pyridin-2(3H)-one

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 1190319-62-0, 6-Bromo-1H-pyrrolo[3,2-b]pyridin-2(3H)-one.

Application of 1190319-62-0, 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 1190319-62-0, name is 6-Bromo-1H-pyrrolo[3,2-b]pyridin-2(3H)-one. This compound has unique chemical properties. The synthetic route is as follows.

Add the compound 1E (10 g, 46 mmol) obtained in the previous step to DMF (100 ml), and then add potassium carbonate (12.8 g, 93 mmol) and(R) -cyclohexyl (phenyl) methyl methanesulfonate (25g, 93mmol) (synthesized according to the method described in patent WO2015100282A1), heating the obtained reaction solution to 60 degrees Celsius, and stirring the reaction overnight,TLC showed that the reaction was completed. The reaction solution was poured into 500 ml of water and extracted with ethyl acetate (2 × 500 mL).The combined organic phases were washed with a saturated sodium chloride solution (3 × 500 mL), the organic phases were dried over anhydrous sodium sulfate,The desiccant was removed by filtration, and the solvent was removed under reduced pressure. The residue was purified by silica gel column chromatography (petroleum ether / ethyl acetate = 3: 1 to 1: 1 (volume ratio V: V)) to obtain the target compound 1F (8.2 g , White solid), yield 46%.

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 1190319-62-0, 6-Bromo-1H-pyrrolo[3,2-b]pyridin-2(3H)-one.
