実験手順

A mixture of methyl 4-((1-benzoylazetidin-3-yl)methoxy)-5-cyclopropyl-2-fluorobenzoate (70 mg, 0.18 mmol) and lithium hydroxide (22 mg, 0.91 mmol) in THF (5 mL) and H2O (10 ml) was stirred at room temperature for 18 h. The mixture was quenched with HCl (1N, 2 mL) and extracted with ethyl acetate (10 mL×3). The combined organic layers were washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated to get the target compound (50 mg, 74%) as a yellow solid. LCMS (ESI) m/z: 370.1 [M+H].
