Procedure

85 mg of 3′-Chloro-6-(3,3-difluoro-cyclobutoxy)-4′-methoxy-biphenyl-3-carboxylic acid methyl ester and 14 mg of LiOH (monohydrate) were dissolved using 5 ml of methanol and 0.5 ml of water. The mixture was stirred for 15 h at room temperature. Then, 14 mg of LiOH (monohydrate) were added and the reaction mixture stirred for 24 h at room temperature. Then, 10 ml of water were added and the methanol evaporated. The mixture was then acidified to pH=2 using aqueous NaHSO4-solution. The mixture was stirred for 30 minutes at room temperature. The product was then collected by filtration and dried in vacuo to yield 65 mg of the title compound that was used without further purification.
