A mixture of 4-methoxyphenylboronic acid (1.51 g, 9.95 mmol), Na2C03 (10.66 ml 2 N aqueous, 21.32 mmol), Pd (PPh3) 4 (0.411 g, 0.355 mmol), 7-bromo-4- methylbenzofuran (1.5 g, 7.11 mmol), and ethylene glycol dimethyl ether (75 ml) was heated to reflux overnight. The reaction was cooled, diluted with EtOAc and the layers separated. The organic layer was dried over anhydrous NA2S04, passed through a silica plug and concentrated. Column chromatography (10percent EtOAc/hexanes) afforded 1.59 g (94percent) product as a white waxy solid: mp 39-40 ¡ãC ; LH NMR (300 MHz, DMSO-d6) : 8 2. 51 (3H, s), 7.07 (2H, d, J = 8. 8 HZ), 7.08 (1H, d, J = 2. 3 HZ), 7.13 (1H, d, J = 7. 7 Hz), 7.37 (IH, d, J 7. 6HZ), 7.79 (2H, d, J = 8. 8 HZ), 8.04 (1H, d, J = 2. 2 HZ) ; MS (ESI) M/Z 239 ([M+H]+). Anal. for C16H1402 : Calc’d: C: 80. 65 H: 5.92 Found: C: 80. 89 H: 5.85
