In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 199786-58-8 as follows. Computed Properties of C7H6BrIO
A solution of oxalyl chloride (1.53 g, 0.012 mol) in CH2Cl2 (15 ML) was cooled to -70 C., and DMSO (1.41 g, 0.018 mol) in CH2Ck (15 ML) was added at -65 to -70 C. The mixture was stirred under nitrogen for 10 minutes at -70 C. and then treated with the product from Example 62B (2.35 g, 7.5 mmol) in 60 ML CH2Cl2.The slurry was stirred at -65 C. for 15 minutes and treated with triethylamine (3.8 g, 0.037 mol).The mixture was allowed to warm to -10 C. over 1 hour.The mixture was treated with 20 ML of water and allowed to warm to room temperature.The organic layer was separated and concentrated to provide the title compound. 1H NMR (CDCl3, 400 MHz) delta 9.97 (s, 1H), 7.97 (d, J=4 Hz, 1H), 7.79 (d, J=8 Hz, 1H), 7.40 (dd, J=4, 8 Hz, 1H). MS (DCl/NH3) [M+NH4]+ at 328.
According to the analysis of related databases, 199786-58-8, the application of this compound in the production field has become more and more popular.
