Potassium Carbonate → 4-[4-(11-Bromo-undecyloxy)-phenyl]-cyclohexanol

Participants

Reaction Steps

A mixture of 2.40 g (0.012 mol) of 4-(4-Hydroxy-cyclohexyl)-phenol obtained in Step 1, 11.76 (0.037 mol) of 1,11-Dibromoundecane, 5.17 g (0.037 mol) of K2CO3 and 40 mL of dry butanone is refluxed for 24 h, then allowed to return to room temperature. The reaction mixture is filtered off and the butanone is distilled off under reduced pressure. The crude product is purified by recrystallisation from ethanol to give a pure product as a white solid (4.34 g, 85% yield).
