Synthesis
To a stirred mixture of anhydrous N,N-dimethylformamide (5 ml) containing 2-(1-adamantyl)-4-bromophenol (0.5 g; 1.62 mmol) and anhydrous potassium carbonate (0.335 g; 2.42 mmol), iodomethane (1 ml) was added. The reaction mixture was stirred at room temperature for 2 hours. After completion of the reaction, the mixture was diluted to 100 ml with distilled water and extracted with ethyl acetate (100 ml). The organic layers were combined, dried with anhydrous magnesium sulfate and filtered to remove the desiccant. The filtrate was filtered through silica gel column to remove impurities. Finally, the filtrate was concentrated to dryness under reduced pressure to give 1-(5-bromo-2-methoxyphenyl)adamantane (0.49 g, 94% yield) as a light yellow-green solid.1H-NMR (CDCl3) δ: 7.27-7.22 (m, 2H); 6.31 (d, 1H, J = 6.5 Hz); 3.78 (s, 3H); 2.04 (s, 10H). 1.74 (br, 5H).
