실험 절차
To a solution of ethyl 1-({5-[5-(4-cyclohexylphenyl)-1,2,4-oxadiazol-3-yl]-2-furyl}methyl)azetidine-3-carboxylate (0.23 g, 0.53 mmol) that was obtained in Example 2 (2d) in a mixed solvent of tetrahydrofuran (0.50 ml), methanol (0.50 ml) and water (0.50 ml) was added lithium hydroxide monohydrate (50 mg, 1.2 mmol) with stirring, and the resulting mixture was stirred at room temperature for 1 hour. After stirring, acetic acid (65 μl, 1.2 mmol) was added to the reaction mixture to quench the reaction. The white solid precipitated was collected by filtration using a Kiriyama funnel, washed with a mixed solvent of water and methanol (3:7) and dried in vacuo to afford the title compound (122 mg) in a yield of 56% as a white crystalline solid.
