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 99835-27-5 as follows. Computed Properties of C7H2BrCl2N
Synthesis of compound 9.3. To a solution of compound 9.2 (1.6 g, 6.37mmol, 1.0 equiv) in toluene (28 mL) was added ammonium chloride (1.7g, 31.8mmol, 5.0 equiv) at room temperature. Trimethylaluminum solution (2M in toluene) (2.29g, 31.8 mmol, 5.0 equiv) was added slowly under a nitrogen atmosphere. The mixture was heated at 110 C for 48 hrs. Upon completion, the reaction mixture was cooled to room temperature and silica was added followed by chloroform (50 mL). The resulting suspension was stirred for 30 minutes, filtered and the filter cake washed with 20% methanol in dichloromethane. The filtrate was concentrated under reduced pressure to obtain crude material, which was triturated with 10% ethyl acetate in hexane to yield compound 9.3 (1.6 g, 93%). MS (ES): m/z 269 [M+H]+.
According to the analysis of related databases, 99835-27-5, the application of this compound in the production field has become more and more popular.
