実験手順

To a solution of 4-biphenylacetic acid (10 g, 47 mmol) in methanol (150 mL) was added concentrated HCl (3 mL). The mixture was heated under reflux for 16 hours, cooled to rt, and the solvent was evaporated. Chromatography of the residue over silica gel (petroleum ether followed by ethyl acetate/petroleum ether 1/4) gave 4-biphenylacetic acid methyl ester (10.4 g, 98%).
