Introduction of a new synthetic route about 6-Bromopyridine-2-sulfonamide

With the rapid development of chemical substances, we look forward to future research findings about 856013-04-2.

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 856013-04-2, name is 6-Bromopyridine-2-sulfonamide. This compound has unique chemical properties. The synthetic route is as follows. category: pyridine-derivatives

c) 6-(8-Oxo-5,6,7,8-tetrahydro-naphthalen-2-yl)-pyridine-2-sulfonamide6-Bromo-pyridine-2-sulfonamide (65mg, 0.27 mmol), 7-(4,4,5,5-Tetramethyl- [l,3,2]dioxaborolan-2-yl)-3,4-dihydro-2H-naphthalen-l-one (97mg, 0.36 mmol), tetrabutylammonium bromide (TBAB) (lOmg, 0.04 mmol) and Pd(PPh3)2Cl2 (13mg, 0.02 mmol) in dioxane:water (1.2 mL/0.6 mL) were heated at 1000C in a microwave reactor for 1 hour. After this time, water was added and the aqueous phase was extracted three times with ethyl acetate. The combined organic phases were washed with water and brine and dried over Na2SO4. Concentration afforded a brown solid which was triturated with Et2O. An off-white solid was obtained. Analysis (NMR) showed presence of impurities but the compound was on-reacted without further purification. NMR 1H (d6-DMSO, ppm): 8.6 (d, J = 2.1 Hz, IH), 8.36 (dd, J = 8.1 and 2.1 Hz, IH), 8.20 (dd, J = 9.03 and 1 Hz, IH), 8.11 (t, J = 7.6 Hz, IH), 7.85 (dd, J = 7.6 and 1 Hz, IH), 7.53-7.50 (m, 3H), 3.01-2.98 (m, 2H), 2.66-2.62 (m, 2H), 2.10-2.04 (m, 2H).

With the rapid development of chemical substances, we look forward to future research findings about 856013-04-2.
