Procedure

3-(1-adamantyl)-4-methoxyphenylboronic acid (150 mg, 0.32 mmol), 6-bromo-2-naphtalenyl trifluoromethanesulphonate (93 mg, 0.26 mmol), K3PO4 (222 mg, 1.05 mmol), KBr (34 mg, 0.29 mmol) and THF (2 ml) were introduced into a Schlenk tube. Next, the reaction mixture was deoxygenated (3 froze/thaw cycles). Next, Pd(PPh3)4 (15 mg, 0.013 mmol) was added and the mixture was again deoxygenated (2 froze/thaw cycles). After heating at reflux for 18 h, the mixture was brought at room temperature and was diluted with CHCl3 (5 ml). The solution was filtered through celite and washings with CHCl3 (2×5 ml) were carried out. The evaporation of the joined organic phases gave a residue which was redissolved in CHCl3 (5 ml) and washed with H2O (2×5 ml). The organic phase was dried with Na2SO4 and after evaporation to dryness, a crude was obtained (97 mg) which was recrystallized with the minimum volume of toluene at reflux. The title compound was obtained (68 mg, 58%) as a pale yellow powder. IR (KBr) 2900, 2847, 1600, 1489, 1456, 1442, 1262, 1237, 1178, 1142, 1103, 1061, 1026, 877, 809 y 470. M/Z (El) 448 [M+ (81Br), 76%] y 446 [M+ (79Br), 100].
