Simple exploration of 73918-56-6

The synthetic route of 73918-56-6 has been constantly updated, and we look forward to future research findings.

73918-56-6, A common heterocyclic compound, 73918-56-6, name is 2-(4-Bromophenyl)ethanamine, molecular formula is C8H10BrN, 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.

To a solution of 4-bromophenethylamine (5.00 g, 25.0 mmol), potassium carbonate (5.18 g, 37.5 mmol) in CH2Cl2 (125 ml) was stirred for 15 min at room temperature, and boc anhydride was added (6.04 mL, 26.3 mmol). After 16 h, the reaction mixture was washed with H2O (125 mL 3) and brine (75 mL). The organic layer was dried with anhydrous Na2SO4 and concentrated in vacuo. The residue was washed with n-hexane and gave 13 as a white solid (6.63 g, 88%); Rf = 0.50 (EtOAc 1: n-Hexane 3); 1H NMR (300 MHz, DMSO-d6) delta 1.43 (s, C(CH3)3), 2.75 (t, J = 6.6 Hz, NHCH2CH2), 3.34-3.35(m, NHCH2CH2), 7.06 (d, J = 8.0 Hz, 2 ArH), 7.42 (d, J = 8.2 Hz, 2 ArH); 13C NMR (75 MHz, DMSO-d6) delta 28.4 (C(CH3)3), 35.7 (NHCH2CH2), 41.6 (NHCH2CH2), 79.3 (C(CH3)3), 120.2, 130.6, 131.6, 138.0 (6 ArC), 155.8 (C(O)).

The synthetic route of 73918-56-6 has been constantly updated, and we look forward to future research findings.
