Методика

Coupling of 3-bromophenol (17) (5.0 g, 28.9 mmol) with 2-ethylbutan-1-ol (3.25 g, 31.79 mmol) was conducted following the procedure given for Example 6. The reaction mixture was concentrated under reduced pressure then triturated with diethyl ether. The suspension was filtered and the filtrate was concentrated under reduced pressure. Purification by flash chromatography (100% hexanes) gave 1-bromo-3-(2-ethylbutoxy)benzene a clear liquid. Yield (5.04 g, 62%): 1H NMR (400 MHz, DMSO-d6) δ 7.20 (t, J=8.0 Hz, 1H), 7.11 (t, J=2.2 Hz, 1H), 7.07 (dd, J=8.0, 2.0 Hz, 1H), 6.92 (dd, J=8.4, 2.6 Hz, 1H), 3.84 (d, J=5.6 Hz, 2H), 1.61-1.53 (m, 1H), 1.46-1.30 (m, 4H), 0.86 (t, J=7.4 Hz, 6H).
