Reaction Steps

A mixture of [4-chloro-3-[2-(2,6-dimethyl-4-phenyl carbamoyl piperazine-1-yl)ethoxy]phenyl]acetic acid methyl ester (50 mg), 2N sodium hydroxide (0.1 mL) and tetrahydrofuran (1 mL) was stirred at room temperature for 4 hours. After neutralizing with 2N hydrochloric acid, the mixture was extracted with ethyl acetate. The organic layer was washed with brine, and dried over magnesium sulphate. The solvent was evaporated under reduced pressure. The residue was purified by column chromatograph on silica gel to give the title compound (18 mg). Yield: 37%.
