Adding a certain compound to certain chemical reactions, such as: 10269-01-9, name is (3-Bromophenyl)methanamine, belongs to bromides-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 10269-01-9, Quality Control of (3-Bromophenyl)methanamine
A mixture of (3-bromophenyl)methanamine (5.4 g, 29 mmol), AcCl (2.7 g, 29 mmol) and Et3N (5.9 g, 58 mmol) in DCM (100 mL) was stirred at rt for 3 h, then it was quenched with water (20 mL) and extracted with DCM (3 x 20 mL). The combined organic layers were concentrated in vacuo. The residue was recrystallized from hexanes/EtOAc (10/1, 55 mL) to afford the title compound. 1H NMR (CDC13, 400 MHz): delta 7.40-7.36 (m, 2H), 7.20- 7.15 (m, 2H), 6.01 (br s, 1H), 4.37 (d, / = 6.0 Hz, 2H), 2.01 (s, 3H).
