Application of 5-Bromo-3-methyl-1H-pyrrolo[2,3-b]pyridine

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 1111637-94-5, 5-Bromo-3-methyl-1H-pyrrolo[2,3-b]pyridine, other downstream synthetic routes, hurry up and to see.

Application of 1111637-94-5, Adding some certain compound to certain chemical reactions, such as: 1111637-94-5, name is 5-Bromo-3-methyl-1H-pyrrolo[2,3-b]pyridine,molecular formula is C8H7BrN2, 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 1111637-94-5.

Step 7: 3-methyl-5-(4,4,5,5-tetramethyl-l,3,2-dioxaborolan-2-yl)-lH-pyrrolo[2,3-b]pyridine To a solution of 5-bromo-3-methyl-lH-pyrrolo[2,3-b]pyridine (20 g, 94.8 mmol) in N,N- dimethylformamide (200 mL) was added potassium acetate (27.9 g, 284.4 mmol) and 4,4,4′,4′,5,5,5′,5′-octamethyl-2,2′-bi(l,3,2-dioxaborolane) (28.8 g, 113.74 mmol). The resulting mixture was degassed with nitrogen for 5 min, l,l’-Bis(diphenylphosphino)ferrocene- palladium(II)dichloride (6.65g, 9.48mmol) was added and the mixture was degassed with nitrogen once more for 5 min. The reaction mixture was stirred overnight at 80-90 C. The reaction mixture was poured into water, extracted with (3 x 200 mL). The combined organic layers were washed with brine, dried over sodium sulfate and concentrated to dryness in vacuo. The resulting residue was purified by column chromatography (silica gel, 100-200 mesh, 9% to 50% ethyl acetate in petroleum ether) affording 3-methyl-5-(4,4,5,5-tetramethyl-l,3,2-dioxaborolan-2-yl)-lH-pyrrolo[2,3-b]pyridine as a white solid (10.5 g, 43%): lU NMR (400MHz, DMSO-d6), delta 11.360 (s, 1H), 8.371-8.375 (d, = 1.6 Hz, 1H), 8.097-8.100 (s, = 1.2 Hz, 2H), 7.17 (s, 1H), 3.296 (s, 3 H), 1.245 (s, 12H).

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 1111637-94-5, 5-Bromo-3-methyl-1H-pyrrolo[2,3-b]pyridine, other downstream synthetic routes, hurry up and to see.
