In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 619331-71-4, name is 4,7-Dibromo-1H-pyrrolo[2,3-c]pyridine, the common compound, a new synthetic route is introduced below. COA of Formula: C7H4Br2N2
A mixture of 4,7-dibromo-lH-pyrrolo[2,3-c]pyridine (207 mg, 0.75 mmol), 1- tetrahydropyran-2-yl-4-(4,4,5,5-tetramethyl-l,3,2-dioxaborolan-2-yl)pyrazole (250 mg, 0.90 mmol), (63 mg, 0.076 mmol), and K2CO3 (0.94 mL, 1.9 mmol, 2.0 M) in DMF (4.0 mL) was stirred at 60 C for 24 h under argon. After cooling, the solvent was evaporated and the residue was chromatographed on a silica gel column (ethyl acetate in dichloromethane 0-100%) to provide 4-bromo-7-(l-tetrahydropyran-2-ylpyrazol-4-yl)-lH-pyrrolo[2,3-c]pyridine (229 mg, 88%). LC-MS 347.1, 349.1 [M+H]+, RT 0.98 min.
The synthetic route of 619331-71-4 has been constantly updated, and we look forward to future research findings.
