Reference of 55289-36-6,Some common heterocyclic compound, 55289-36-6, name is 3-Bromo-2-methylaniline, molecular formula is C7H8BrN, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Under nitrogen atmosphere, 3-bromo-2-methylaniline (5.01g, 26.9 mmol) was dissolved in DCM (100 mL). To this solution, cooled with ice bath, TEA (7.5 mL, 53.9 mmol) and 4-tert-butylbenzoyl chloride (5.3 g, 26.9 mmol) were added dropwise and stirred at 0 C for 4 h. The reaction mixture was diluted with DCM (100 mL), washed with water (2×30 mL), 1N hydrochloric acid solution (30 mL), saturated sodium hydrogen carbonate solution (30 mL) and brine (30 mL), then the organic layer was dried over sodium sulfate, filtered and concentrated. The crude material was suspended in hexane, then the precipitate was collected by filtration, washed with hexane then dried to afford N-(3-bromo-2-methylphenyl)-4-(tert-butyl)benzamide (9.0 g). 1H NMR (400 MHz, DMSO-d6) delta 10.06 (s, 1H), 7.92 (d, J = 8.4 Hz, 2H), 7.54 (m, 3H), 7.33 (d, J = 7.7 Hz, 1H), 7.18 (t, J = 8.0 Hz, 1H), 2.27 (s, 3H), 1.32 (s, 9H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3-Bromo-2-methylaniline, its application will become more common.
