The mixture was heated at 40 0C for 4 hours. At the conclusion of this period, the reaction was worked up by adding water and adjusting the pH to 3 with IN HCl. The aqueous mixture was extracted (3X) with EtOAc/THF. The organic layers were rinsed (3X) with water. The organic layer was dried over sodium sulfate and concentrated to give an off-white solid. The solid was stirred in hexanes (10 mL), filtered and dried under high vacuum to give 3 '-(methoxycarbonyl)biphenyl-3- carboxylic acid (860 mg, 3.36 mmol, 83% yield) as a white solid. MS (ESI+) = 257.23 (M+H)+

The solids were purged with nitrogen for about ten minutes, then 1,4-dioxanes (5 ml) and water (0.25 ml) was added, and nitrogen bubbled through for about ten minutes. Then the mixture was heated and allowed to reflux (about one to two hours was required for complete consumption of aryl bromide). The crude was then subjected to MPLC (in this case, 0 to 60% ethyl acetate in hexanes) to afford 234 mg of material (80%). The ester was then hydrolyzed using ten equivalents of 5 M NaOH in THF, which required two hours of stirring for complete hydrolysis, yields are typically between 90 and 99% following removal of THF, acidification with HCl (resulting in a solid which can be collected), and drying: 1H NMR (300 MHz, DMSO-d6)d 8.25 (bs, 1H), 8.15 (bs, 1H), 8.02 - 7.95 (m, 3H), 7.86 - 7.83 (m, 1H), 7.68 (q, J = 7.8 Hz, 2H), 7.45 (s, 2H).
