These common heterocyclic compound, 53087-13-1, name is 1-(Benzyloxy)-3-bromobenzene, 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. SDS of cas: 53087-13-1
3′-Benzyloxy-biphenyl-3-carboxylic acid methyl ester (29) A degassed mixture of 3-benzyloxy-phenyl bromide (28) (0.176 g, 0.67 mmol), 3-methoxycarbonylphenylboronic acid (0.18 g, 1 mmol), barium hydroxide (0.25 g, 1.47 mmol), Pd(PPh3)4 (0.077 g, 0.067 mmol), DME (5 mL) and H2O (3 mL) was microwaved with vigorous stirring using a CEM-discover system (ram time: 2 min, hold time: 5 min, temperature: 120 C., pressure: 200 psi, power: 250 W). The crude reaction mixture filtered through a plug of celite and concentrated in vacuo. The residue obtained was purified by flash column chromatography (25% diethyl ether-hexane) to give the title compound (29) (0.118 g, 60% yield) as a viscous liquid. 1H NMR (500 MHz, CDCl3) delta 8.27 (t, J=1.5 Hz, 1H), 8.20 (dd, J=8.0 Hz, J=1.5 Hz, 1H), 7.76 (dd, J=8.0 Hz, J=2.0 Hz, 1H), 7.50 (t, J=8.0 Hz, 1H), 7.47 (d, J=7.5 Hz, 2H), 7.42-7.32 (m, 4H), 7.25-7.22 (m, 2H), 7.00 (dd, J=8.2 Hz, J=2.0 Hz, 1H), 5.13 (s, 2H), 3.95 (s, 3H).
The synthetic route of 1-(Benzyloxy)-3-bromobenzene has been constantly updated, and we look forward to future research findings.
