The crude product of the title compound was synthesized by conducting the reaction similar to that mentioned in Example 1 (1f) using {5-[5-(3-fluoro-4-phenoxyphenyl]-1,2,4-oxadiazol-3-yl)-4-methyl-2-thienyl}methanol (0.21 g, 0.55 mmol) that was obtained in Example 11 (11f), carbon tetrabromide (0.22 g, 0.66 mmol), triphenylphosphine (0.17 g, 0.66 mmol), methyl 3-azetidinecarboxylate hydrochloride (0.13 g, 0.83 mmol), and N,N-diisopropylethylamine (0.30 mL, 1.7 mmol). Subsequently, the crude product of the title compound thus obtained was purified by chromatography using a mixed solvent of ethyl acetate and hexane (5:5) to afford the title compound (0.23 g) in a yield of 86% as a colourless oily product.
