72678-19-4, name is 2,6-Dibromo-4-(trifluoromethyl)aniline, belongs to bromides-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Quality Control of 2,6-Dibromo-4-(trifluoromethyl)aniline
General procedure: A suspension of potassium hydride (3 equiv) in THF (0.6 M) was cooled in an ice-water bath. A solution of sulfonamide, sulfonamide or aniline (1.0 equiv) in THF (0.20 M) was added dropwise, and the suspension was stirred for 15 min. 1,1′-Carbonyldiimidazole (1.0 equiv) was dissolved in 1:1 THF/dioxane (0.20 M) and added dropwise to the reaction mixture, resulting in the formation of a white precipitate. The ice-water bath was removed, and the reaction mixture was allowed to warm to ambient temperature and was stirred for 2 h. A solution of diamine S-1 (1.0 equiv) in THF (1.0 M) was added dropwise, and the suspension was stirred at room temperature for 20 h. The reaction was quenched with a solution of acetic acid (3 equiv) in THF (1.0 M). The crude product was concentrated in vacuo and purified by silica gel chromatography.
The synthetic route of 72678-19-4 has been constantly updated, and we look forward to future research findings.
