Procedure

To a solution of potassium tert-butoxide (818 mg, 7.29 mmol) in toluene (45 mL) was added methyl triphenylphosphonium iodide (2.94 g, 7.29 mmol) and the resulting mixture was stirred at 120° C. for 1 hour under an argon atmosphere. To the reaction solution was added N-(3-(4-acetyl-3-methoxyphenyl)-4,6,7-trimethyl-2,3-dihydro-1-benzofuran-5-yl)-3,3-dimethylbutanamide (2.32 g, 5.48 mmol) obtained in Example 183 and the resulting mixture was stirred at 120° C. for 2 hours. Water was added to the reaction solution, the organic layer was separated, and the aqueous layer was extracted with ethyl acetate. The combined organic layers were dried over anhydrous sodium sulfate and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate:hexane=2:3) to obtain 1.93 g (yield: 84%) of the title compound. Melting point: 186-187° C. (ethyl acetate-hexane).
