实验步骤: A mixture of 3-cyclopropyl-3-methylbutyric acid ethyl ester (3.0 g, 17.6 mmol) and lithium hydroxide monohydrate (3.5 g, 105 mmol) in THF/H2O/MeOH (24 mL, 2:1:1 v/v) was stirred at rt overnight. The reaction mixture was diluted with water (100 mL), and washed with ethyl acetate (2×50 mL). The aqueous layer was acidified with 2M HCl and extracted with ethyl acetate (3×100 mL). The combined organic extracts were washed with brine (200 mL), dried over sodium sulfate and concentrated to give 3-cyclopropyl-3-methylbutyric acid. washed with ethyl acetate (2×50 mL) extracted with ethyl acetate (3×100 mL) The combined organic extracts were washed with brine (200 mL) dried over sodium sulfate concentrated
