Reaction Steps

A solution of 2-(3-iodophenoxymethyl)-naphthalene (0.5 g, 1.4 mmol) and hexynoic acid (0.19 g, 1.7 mmol) in piperidine (5 mL) is purged with Argon for 20 minutes. Then bis(triphenylphosphine)palladium dichloride (0.01 g, 0.014 mmol) and cuprous iodide (0.005 g, 0.028 mmol) are added and this mixture heated in an oil bath at 75° C. for 1.5 hours and then allowed to come to room temperature overnight. The solvent was removed in vacuo and the residue purified by flash chromatography (silica, 4% methanol in dichloromethane) to give the title compound. 1H NMR (300 MHz, CDCl3) δ 7.83-7.88 (m, 4H), 7.48-7.54 (m, 3H), 7.19 (t, 1H), 6.98-7.05 (m, 3H), 5.21 (s, 2H), 2.47 (t, 2H), 1.80-1.91 (m, 4H); MS (EI) 344 (M)+.
