Electric Literature of 10269-01-9, A common heterocyclic compound, 10269-01-9, name is (3-Bromophenyl)methanamine, molecular formula is C7H8BrN, its 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.
General procedure: (c) A solution of Boc2O (1.29g, 5.91mmol) in CH2Cl2 (10ml) was added to a suspension of 4-bromobenzylamine (1.00g, 5.38mmol) and Et3N (0.60g, 5.91mmol) in CH2Cl2 (10ml) for 5min at 0C with a CaCl2 tube. The reaction mixture was stirred overnight at room temperature. Then, H2O (50ml) was added to the mixture, and the organic layer was separated. The aqueous layer was extracted with CHCl3 (50ml×3). The combined organic layer was washed with H2O (50ml×1) and then brine (50ml×1), dried over Na2SO4 (anhyd), filtered, and concentrated under reduced pressure to afford (4-bromobenzyl)carbamic acid tert-butyl ester (1.63g, quant. y.) as a colorless solid.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
