実験手順
A mixture of 6-bromo-2-naphthaldehyde (1.17 g, 4.98 mmol, see Example 3c), 3-(1-adamantyl)-4-methoxyphenyl boronic acid (1.57 g, 5.48 mmol, prepared in a manner similar to that described in Example 3b.) and potassium carbonate (1.55 g, 11.20 mmol) in 75 mL of toluene and water (4 mL) was degassed with argon for 30 minutes . Tetrakis(triphenyl phosphine)palladium(0) (0.575 g, 0.50 mmol) was added and the mixture heated at reflux for 18 hours. The solution was cooled to room temperature, diluted with ethyl acetate and washed successively with water and brine, dried over anhydrous magnesium sulfate, filtered and evaporated. The residue was purified on silica gel (eluent: hexane:CH2Cl2, 3:2 to 1:1) to give 1.6 g of 6-[3-(1-adamantyl)-4-methoxyphenyl]-2-naphthaldehyde (82%) as a solid. 1H NMR (300 MHz; CDCl3): δ 1.80 (s, 6H), 2.10–2.17(m, 9H), 3.90 (s, 3H), 6.99 (d, J=8.1 Hz, 1H), 7.52–7.60 (m, 2H), 7.82 (d, J=8.4 Hz, 1H), 7.95–8.02 (m, 4H), 8.32 (s, 1H), 10.13 (s, 1H).
