Participants

Reaction Steps

To a solution of 4-bromo-2-methoxyphenol (2.87 g, 14.13 mmol) in DMF (20 ml) was added ethyldiisopropylamine (6.15 ml, 35.32 mmol). The clear solution was stirred for 5 min. followed by addition of tert-butylchlorodimethylsilane (2.56 g, 16.95 mmol). The crude was purified via flash column chromatography (100% in hexane) to give (4-bromo-2-methoxy-phenoxy)-tert-butyl-dimethyl-silane as a clear oil (4.45 g, 99%): 1HNMR (CDCl3) δ 6.95 (s, wide, 1H, Ar), 6.92 (d, J=2 Hz, 1H, Ar), 6.71 (d, J=7 Hz, 1H, Ar), 3.79 (s, 3H, OCH3), 0.98 (s, 9H, 3CH3), 0.13 (s, 6H, 2CH3). The product was carried over to the next step.
