PROCEDURE

实验过程

2-(5-Trifluoromethyl-pyridin-2-yl)-benzoic acid isopropyl ester was dissolved in 10 ml of a 3:1:1 mixture of tetrahydrofuran-methanol-water, and lithium hydroxide monohydrate (161 mg, 3.84 mmol) was added. After stirring for 3 h at room temperature, the volatiles were removed under vacuum and 5 ml of water were added to the mixture, which was brought to pH 6 with 1N HCl. The resulting slurry was extracted with ethyl acetate, the combined organic layers were dried (magnesium sulfate), filtered and concentrated under vacuum to provide the title compound.
