Procedure
To a solution of 2-(5-(4-fluoro-benzyl)-thiophen-2-yl)-[1,3]dioxolane described in Preparation Example 36 (560 mg, 2.04 mmol) in methanol (20 mL) was added citric acid aqueous solution (20 mL), and the solution was stirred at room temperature for 30 minutes. Ethyl acetate and water were added to the reaction solution, which was then partitioned, the organic layer was washed with water twice, dried over anhydrous sodium sulfate, the solvent was evaporated in vacuo, and title compound (460 mg, 2.09 mmol) was obtained as a brown oil.
