To a mixture of 4′-iodobiphenyl-4-ol (0.332 g, 2 mmol) and 1-admantanol (0.15 g, 0.51 mmol) in AcOH (2 ml) concentrated H2SO4 (0.5 ml) was added and the reaction mixture was stirred for 50 h at room temperature. This was diluted to 100 ml with EtOAc and washed with NaHCO3 solution, dried over MgSO4 and filtered. The filtrate was evaporated to dryness and the residue was crystallized from MeOH to give the product (0.195 g; 93%), as a colourless paste. 1H NMR (CDCl3) 1.78 (m, 6H); 2.07 (s, 3H); 2.15 (s, 6H); 6.69 (d, 1H, J=8.15 Hz); 7.21-7.28 (m, 3H); 7.37 (d, 1H, J=2.28 Hz); 7.69 (d, 2H, J=8.45 Hz).
