Reaction Steps
The crude product of the title compound was synthesized by conducting the reaction similar to that mentioned in Example 1 (1f) using {3-ethyl-5-[5-(4-phenoxyphenyl)-1,2,4-oxadiazol-3-yl]-2-thienyl}methanol (0.19 g, 0.50 mmol) that was obtained in Example 22 (22f), carbon tetrabromide (0.33 g, 0.99 mmol), triphenylphosphine (0.26 g, 0.99 mmol), methyl 3-azetidinecarboxylate hydrochloride (0.11 g, 0.75 mmol), N,N-diisopropylethylamine (0.22 mL, 1.2 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 (2:8 to 4:6) as the eluent to afford the title compound (0.17 g) in a yield of 72% as a pale yellow crystalline solid.
