Методика

Water (39 mL), followed by lithium hydroxide monohydrate (4.2 g, 101.5 mmol) were added to a solution of biphenyl-3-yl acetic acid methyl ester (11.43 g, 50.57 mmol) in methanol (265 mL). The mixture was stirred at ambient temperature for 2 h then the organics were removed under reduced pressure. The mixture was acidified with dilute hydrochloric acid (1M, 80 mL), extracted with chloroform (2×100 mL), dried (MgSO4) and evaporated under reduced pressure to afford biphenyl-3-yl acetic acid as a white solid, yield 10.6 g, (99%), analytical HPLC Rt=16.565 min, HPLC-MS (single main UV peak with Rt=7.91 min, 213.1 [M+H]+).
