실험 절차

Methyl 4-t-butylphenylacetate (20 mmol) was dissolved in MeOH (160 mL) and treated with water (40 mL) and LiOH monohydrate (30 mmol). The reaction was allowed to stir at room temperature overnight. Volatiles were removed under reduced pressure, the remaining residue was diluted with water and neutralized to ph 4 with 1 N sulfuric acid. The resulting solids were filtered, washed with water and dried to leave 4-t-butylphenylacetic acid as an off-white solid (3.8 g, 99%).
