Related Products of 112734-22-2, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 112734-22-2, name is (4-Bromo-2-fluorophenyl)methanamine, This compound has unique chemical properties. The synthetic route is as follows.
To a solution of (4-bromo-2-fluorophenyl) methanamine (2.5 g, 12 mmol) in DCM (50 mL) at 0 C was added di-terf-butyl dicarbonate (4.01 g, 18 mmol) and triethylamine (2.6 mL, 18 mmol). The mixture was allowed to warm to room temperature and stirred for 2h. Water was added (50 mL) and the layers were separated. The organic layer was washed with brine, dried over sodium sulfate and concentrated in vacuum. The crude product was purified by flash silica column chromatography (heptane:ethyl acetate) (1 :0 to 4:1 ) to afford the title compound as a colorless oil. (2.7 g, 71 %).1 H NMR (400 MHz, DMSO-d6) delta ppm 7.21 -7.26 (m, 3 H), 4.90 (br s, H), 4.27-4.33 (m, 2 H), 1 .44 (s, 9 H).
The chemical industry reduces the impact on the environment during synthesis (4-Bromo-2-fluorophenyl)methanamine. I believe this compound will play a more active role in future production and life.
