Procedure

A solution of 3′-methyl-[1.1′-biphenyl]-4-carboxylic acid ethyl ester of Step A (3.3 g, 13.7 mmol) in tetrahydrofuran (40 mL) and 1 N sodium hydroxide (27.5 mL, 27.5 mmol) was heated at reflux overnight. After cooling, the reaction was concentrated in vacuo. The residue was acidified with 2N hydrochloric acid to yield a white solid which was collected by filtration and dried under vacuum to provide the title compound (2.9 g, 99.7%) as a white solid, m.p. 198-200° C.
