Reaction Steps

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-benzylphenyl)-1,2,4-oxadiazol-3-yl]-2-thienyl}methanol (95 mg, 0.27 mmol) that was obtained in Example 6 (6a), carbon tetrabromide (0.18 g, 0.54 mmol), triphenylphosphine (0.14 g, 0.54 mmol), ethyl 3-azetidinecarboxylate hydrochloride (67 mg, 0.41 mmol), and N,N-diisopropylethylamine (0.12 ml, 0.68 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 (6:4) as the developing solvent to afford the title compound (84 mg) in a yield of 68% as a white crystalline solid.
