Adding a certain compound to certain chemical reactions, such as: 702641-04-1, name is 2-Iodo-5-(trifluoromethyl)benzoic 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 702641-04-1, Application In Synthesis of 2-Iodo-5-(trifluoromethyl)benzoic acid
To a cooled (ice water bath) mixture of 2-iodo-5-(trifluoromethyl)benzoic acid (2.5 g, 7.9 mmol) in tetrahydrofuran (50 mL) and methanol (10 mL) was added dropwise a 0.6 M solution of trimethylsilyldiazomethane in hexane (TCI America, 16 mL, 9.9 mmol) via syringe. After LC/MS analysis confirmed the consumption of the starting acid, acetic acid (approximately 3 mL) was added. The mixture was concentrated under reduced pressure, and the putative desired intermediate was carried forward without further purification.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2-Iodo-5-(trifluoromethyl)benzoic acid, and friends who are interested can also refer to it.
