Participants

Reaction Conditions

Reaction Steps

Sodium hydroxide (5M; 4.7 mL; 23.4 mmol; 3 eq.) was added to a solution of methyl 2′-methoxy-2-methylbiphenyl-4-carboxylate (2 g; 7.8 mmol; 1 eq.) in EtOH (60 mL) and the reaction mixture was stirred at 60° C. for one hour then concentrated in vacuo. The residue was taken up in water (400 mL) and washed with ethyl acetate (2×200 mL) then acidified to pH 2 with conc. HCl. The solution was concentrated to ca. 80 mL, the precipitate filtered off and dried to afford the title compound as a brown solid.
