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-cyclohexylphenyl)-1,2,4-oxadiazol-3-yl]-2-furyl}methanol (0.18 g, 0.55 mmol) that was obtained in Example 2 (2c), carbon tetrabromide (0.22 g, 0.67 mmol), triphenylphosphine (0.18 g, 0.67 mmol), ethyl 3-azetidinecarboxylate hydrochloride (0.14 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 on a silica gel column using a mixed solvent of ethyl acetate and hexane (1:1 to 2:1) as the eluent to afford the title compound (0.23 g) in a yield of 96% as a white crystalline solid.
