Imidazole → 4-Bromobenzyloxy-tert-butyldimethylsilane

Participants

Reaction Steps

To a solution of (4-bromophenyl)methanol (3.0 g, 16.04 mmol) and imidazole (1.42 g, 20.85 mmol) in dichloromethane was added tert-butyl dimethylsilyl chloride (3.14 g, 20.85 mmol) and the mixture was stirred at room temperature overnight. The reaction was diluted with water, extracted with ethyl acetate (2×) and concentrated. The residue was absorbed onto silica and purified by flash column chromatography (silica gel, ethyl acetate/hexanes) to give the desired product. 1H NMR (400 MHz, CDCl3) δ 7.45 (d, J=8.4 Hz, 2H), 7.20 (d, J=8.3 Hz, 2H), 4.68 (s, 2H), 0.94 (s, 9H), 0.09 (s, 6H).
