Reaction Steps

0.098 ml of 1 N lithium hydroxide solution was added to a solution of 0.051 g of ethyl 2′,4′-difluorobiphenyl-4-carboxylate in 1 ml THF/water (1:1), and the mixture was stirred at room temperature overnight. 5% hydrochloric acid was used to neutralize the solution, which was concentrated in vacuo, and the residue was purified by preparative HPLC.
