Procedure
4-(3,4,5-Tris-octadecyloxy-cyclohexylmethoxy)-benzaldehyde (130 mg, 127 μmol) was dissolved in dehydrated THF (2 mL), 4-methoxy-phenyl-magnesiumbromide (350 μmol) was added, and the mixture was stirred at 40° C. for 1.5 hr. After evaporation of the solvent, 1N hydrochloric acid (5 mL) was added to the residue to allow crystallization. The crystals were filtered, and thoroughly washed with hydrochloric acid, water and methanol in this order to give (4-methoxy-phenyl)-[4-(3,4,5-tris-octadecyloxy-cyclohexylmethoxy)-phenyl]-methanol (110 mg, 97.2 μmol, 96%).
