実験手順

The title compound (0.17 g) was synthesized in a yield of 74% as a white crystalline solid by conducting the reaction similar to that mentioned in Example 2 (2e) using methyl 1-({5-[5-(3-fluoro-4-phenoxyphenyl)-1,2,4-oxadiazol-3-yl]-4-methyl-2-thienyl}methyl)azetidine-3-carboxylate (0.23 g, 0.48 mmol) that was obtained in Example 11 (11g), lithium hydroxide monohydrate (46 mg, 1.1 mmol), and acetic acid (60 μL, 1.1 mmol).
