Participants

Reaction Steps

1-(2-Chloro-6-fluorophenyl)ethanol (8.5 g), imidazole (8.1 g) and t-butyldimethylsilylchloride (8.71 g) were stirred in DMF for 24 hours. The mixture was diluted with ether and washed with water, dried (anhydrous magnesium sulphate) and filtered. The filtrate was evaporated to dryness to give 1-(2-chloro-6-fluorophenyl)ethyl (t-butyldimethylsilyi)ether (13.3 g) as a clear oil, NMR (CDCl3) -0.1(s,3H), 0.05(s,3H), 0.85(s,9H), 1.5(d,3H), 5.4(q, 1H), 6.9(m, 1H), 7.05(m,2H).
