Isopropanol → 1-bromo-4-propoxybenzene

Participants

Reaction Steps

Prepare a solution of 4-bromo-phenol (17.30 g, 0.10 mol) and potassium carbonate (13.80 g, 0.1 mole) in isopropanol (175 mL). Heat the resulting mixture at reflux and stir overnight. Cool to ambient temperature, filter and condense the filtrate on a rotary evaporator. Dissolve the residual oil in ethyl acetate (250 mL) and extract twice with 5% sodium hydroxide (100 mL), separate and wash with brine. Kugelrohr distillation at 100°-120°, 0.05 mm, gives the title compound (12.86 g, 60%) as a clear liquid.
