Application 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.
26.25g of 3-Bromobenzylamine hydrochloride was suspended in 250 ml of dichloromethane, and the mixture was cooled to 0C. 33.5 g of N,N-diisopropylethylamine and 28.3 g of t-butyl dicarbonate were added. After stirring was continued at room temperature overnight, the reaction mixture was diluted with ethyl acetate. The solution was washed with water and saturated brine, dried over anhydrous magnesium sulfate, filtered, and the solvent was distilled off, to give 31.28 g of the title compound.1H-NMR (CDCl3) delta : 1.45 (s, 9H) 4.28 (d, J=6.0Hz, 2H) 4.87 (brs, 1H) 7. 20 (m, 2H) 7.38 (m, 1H) 7.43 (brs, 1H)
The synthetic route of 10269-01-9 has been constantly updated, and we look forward to future research findings.
