Reaction Steps

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-phenyl-5-(trifluoromethyl)-2-thienyl]-1,2,4-oxadiazol-3-yl}-2-thienyl)methanol (0.12 g, 0.29 mmol) that was obtained in Example 4 (4c), carbon tetrabromide (0.19 g, 0.58 mmol), triphenylphosphine (0.15 g, 0.58 mmol), ethyl 3-azetidinecarboxylate hydrochloride (62 mg, 0.38 mmol), and N,N-diisopropylethylamine (0.13 ml, 0.73 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 (4:5) as the developing solvent to afford the title compound (0.12 g) in a yield of 80% as a colourless oily product.
