실험 절차

A mixture of N-(7-(1-hydroxyethyl)-3-(4-isopropylphenyl)-4,6-dimethyl-2,3-dihydro-1-benzofuran-5-yl)-3,3-dimethylbutanamide (580 mg, 1.37 mmol) obtained in Example 22 and manganese dioxide (1.43 g, 16.4 mmol) were stirred at 100° C. for two hours. Insoluble materials were filtered off, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=4:1) to obtain 440 mg (yield: 76%) of the title compound. Melting point: 200-201° C. (ethyl acetate-hexane).
