Adding a certain compound to certain chemical reactions, such as: 21740-00-1, name is 5-Bromo-2-iodobenzoic acid, belongs to iodides-buliding-blocks compound, 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 21740-00-1, Computed Properties of C7H4BrIO2
General procedure: A sealed tube was charged with CuCl (0.02 mmol), BFMO (0.02 mmol), N-protected N-alkenylhydrazine (2.0 mmol), 2-iodobenzoic acid (2.4 mmol), and K2CO3 (4 mmol). The tube was evacuated and backfilled with argon three times before anhydrous DMSO (4.0 mL) was added via syringe (NOTE: for liquid substrates, they were added into the tube via syringe after the tube was backfilled with argon). The mixture was sealed and stirred at 80 C for 24 h. The mixture was diluted with EtOAc, washed with water, dried over anhydrous sodium sulfate, and filtrated. The filtrate was concentrated in vacuo and the residue was treated with 4M HCl/1,4-dioxane (1.2 mL) at 80 C. After the starting material was completely consumed, the solution was cooled and diluted with EtOAc. The resultant mixture was washed with water and dried over anhydrous sodium sulfate. After the solution was concentratedin vacuo, the residue was purified by flash chromatography to afford the corresponding indole.
