Procedure

To a solution of 6-[3-(1-adamantyl)-4-methoxyphenyl]-naphthalen-2-yl-methyl alcohol (0.365 g, 0.92 mmol), triphenylphosphine (0.366 g, 1.39 mmol) and imidazole (0.095 g, 1.39 mmol) in 7 mL of anhydrous THF at 0° C. was added dropwise a solution of I2 (0.303 g, 1.19 mmol) in 4 mL of anhydrous THF. After 30 minutes the mixture was diluted with EtOAc and washed with sodium thiosulfate aq. (100 mL), brine (100 mL), dried with magnesium sulfate, filtered and evaporated. The residue was purified on silica gel (eluent: hexane:EtOAc 100 to 95:5) to give 0.210 g of 6-[3-(1-adamantyl)-4-methoxyphenyl]-naphthalen-2-yl-methyliodide (45%). 1H NMR (300 MHz; CDCl3): δ 1.80 (s, 6H), 2.10–2.18 (m, 9H), 3.89 (s, 3H), 4.65 (s, 2H), 6.98 (d, J=8.7 Hz, 1H), 7.46–7.57 (m, 3H), 7.71–7.93(m, 5H).
