Methyl 6-(methyloxy)-3-biphenylcarboxylate (D39) (194 mg, 0.8 mmol) dissolved in 2N NaOH aq. (3 ml) and methanol (3 ml). Stirred at room temperature overnight and then the organic solvent was evaporated in vacuo. Added EtOAc/water separated and then acidified the aqueous and re-extracted. The organic extracts were dried and evaporated to afford 202 mg of the title compound as a white solid. δH (d6-DMSO, 400 MHz) 3.84 (3H, s), 7.22 (1H, d), 7.33-7.49 (5H, m), 7.82 (1H, d), 7.95 (1H, dd), MS (ES+): C14H12O3 requires 228; found 229 (M+H+).
