The crude product of the title compound was synthesized by conducting the similar reaction to that mentioned in Example 1 (1f) using {5-[5-(4-phenoxyphenyl)-1,2,4-oxadiazol-3-yl]-2-thienyl}methanol (97 m g, 0.28 mmol) that was obtained in Example 5 (5a), carbon tetrabromide (0.19 g, 0.56 mmol), triphenylphosphine (0.15 g, 0.56 mmol), ethyl 3-azetidinecarboxylate hydrochloride (70 mg, 0.42 mmol), and N,N-diisopropylethylamine (0.18 ml, 1.1 mmol). Subsequently, the crude product of the title compound thus obtained was purified by thin layer chromatography on a silica gel plate using a mixed solvent of ethyl acetate and hexane (4:3) as the developing solvent to afford the title compound (93 mg) in a yield of 72% as a colourless oily product.
