A degassed mixture of pure 6-(6-bromonaphthalen-2-yloxy)hexan-1-ol (5.88 g), 4-[6-(tetrahydropyran-2-yloxy)hexyloxy]phenyl acetylene (6.05 g), triphenylphosphine (0.21 g), copper(I) iodide (0.04 g) and bis(triphenylphosphine)palladium dichloride (0.14 g) in 60 ml of triethylamine was refluxed for 2 hours under an atmosphere of argon. The reaction mixture was cooled and filtered though celite to give a yellowish solution which was then evaporated to dryness to give a yellow residue, which was purified by chromatography using a silica gel column and cyclohexane/ethyl acetate (2:1, 1:1) as eluent, followed by recrystallisation of the resulting solid from cyclohexane/ethyl acetate (100 ml/3 ml) to give 5.10 g of 6-[6-[4-[6-(tetra-hydropyran-2-yloxy)hexyloxy]phenylethyny]naphthalen-2-yloxy]hexan-1-ol as a white powder.
