The crude product of the title compound was synthesized by conducting the similar reaction to that mentioned in Example 1 (1f) using (4-{5-[4-phenyl-5-(trifluoromethyl)-2-thienyl]-1,2,4-oxadiazol-3-yl}-2-thienyl)methanol (0.10 g, 0.25 mmol) that was obtained in Example 3 (3c), carbon tetrabromide (0.17 g, 0.50 mmol), triphenylphosphine (0.13 g, 0.50 mmol), ethyl 3-azetidinecarboxylate hydrochloride (62 mg, 0.38 mmol), and N,N-diisopropylethylamine (0.11 ml, 0.63 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 (2:3) as the developing solvent to afford the title compound (73 mg) in a yield of 56% as a white crystalline solid.
