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. 959992-62-2, name is 6-Bromo-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazine belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Product Details of 959992-62-2
Step 5 To a solution of Compound (10) (2.50 g, 11.6 mmol) in dimethylformamide (20 mL), triethylamine (4.8 mL), 34.9 mmol) and phenylisocyanate (1.6 mL, 15.1 mmol) were added. The solution was then stirred at 25 C for 24 hours. Water (3.0 mL) was then added to the reaction solution. The precipitated powder was filtered, washed with water, and then dried to yield subject compound I-113 (3.4 g, 85%) as a pale brown powder.1H-NMR (DMSO-d6) delta11.92 (1H, s), 7.52-7.55 (2H, m), 7.34-7.40 (3H, m), 7.28 (1H, dd, J = 8.4 Hz, J = 1.5 Hz), 4.30 (2H, t, J = 4.8 Hz), 4.04 (2H, t, J = 4.8 Hz) LC/MS (Method A): 2.45 min, [M+H]+ = 334.0.
The synthetic route of 959992-62-2 has been constantly updated, and we look forward to future research findings.
