Reference of 3959-05-5,Some common heterocyclic compound, 3959-05-5, name is (2-Bromophenyl)methanamine, 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.
Part A. (2-Bromo-benzyl)-methyl-amine A solution of 2-bromobenzylamine (9 g, 36.1 mmol) in MeOH (60 ml) was added dropwise over 30 min. to a solution of methylamine in MeOH (200 mL of a 2.0 M solution, 0.4 mol). The resulting solution was stirred at rt for 2 h and concentrated. The residue obtained was dissolved in DCM (100 mL) and successively washed with saturated aqueous sodium carbonate, dried over sodium sulphate, and concentrated. The resulting oil was distilled to afford the title compound (7 g, 95%) as a colorless oil (b.p. 110 C. at 0.1 mm Hg, LC/MS retention time=1.22 min.; M+=201.92 Column: Phenominex 4.6 mm*50 mm.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route (2-Bromophenyl)methanamine, its application will become more common.
