Procedure

A solution of 6-bromohexan-1-ol (3.64 g, 0.020 mol) from step 1 in butanone (80 ml) was added at room temperature to a stirred mixture of 4-bromo-4-′-hydroxybiphenyl (5.00 g, 0.020 mol) and potassium carbonate (5.50 g, 0.040 mol) in butanone (70 ml). The reaction mixture was heated under reflux for 48 h. The potassium carbonate was filtered off and the solvent was removed in vacuo, the residue was dissolved in diethyl ether (250 ml) and washed with water (2×150 ml) and dried (MgSO4). The solvent was removed in vacuo and the crude solid was then recrystallised from ethanol to give white crystals.
