Reaction Steps

The crude product of the title compound was synthesized by conducting the reaction similar to that mentioned in Example 1 (1f) using (5-{5-[4-(2-chlorophenoxy)phenyl]-1,2,4-oxadiazol-3-yl}-4-ethyl-2-thienyl)methanol (0.19 g, 0.46 mmol) that was obtained in Example 19 (19b), carbon tetrabromide (0.18 g, 0.55 mmol), triphenylphosphine (0.14 g, 0.55 mmol), methyl 3-azetidinecarboxylate hydrochloride (0.10 g, 0.69 mmol), and N,N-diisopropylethylamine (0.16 mL, 0.92 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 (0.21 g) in a yield of 91% as a pale yellow oily product.
