Electric Literature of 55304-80-8, Adding some certain compound to certain chemical reactions, such as: 55304-80-8, name is 2,6-Dibromo-3-nitropyridine,molecular formula is C5H2Br2N2O2, 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 55304-80-8.
N, N-Dimethyl-N’- (6-bromo-3-nitropyridin-2-yl) sulfonic acid Stir a mixture of 2,6-dibromo-3-nitropyridine (11. 3g, 39.25 mmol) and N, N- dimethylsulfamide (0.006 g, 47.10 mmol) in DMF (40 mL). Add lithium hydride (0.81 g, 102.05 mmol) and stir at RT overnight. Add 100 mL of water and 3 N HC1 until pH = 7. Filter the yellow solid to provide the title compound (93%). 1H NMR (DMSO-d6) 8 10.25 (br s, 1H), 8.41 (d, J= 8.59 Hz, 1H), 7.50 (d, J= 8.59 Hz, 1H), 2.95 (2,6H).
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. 55304-80-8, 2,6-Dibromo-3-nitropyridine, other downstream synthetic routes, hurry up and to see.
