実験手順

To a solution of 8-(1-(4-methoxyphenyl)-5-(p-tolyl)-1H-pyrazol-3-yl)-1,4-dioxaspiro[4.5]decan-8-ol (Reference Example 30) (14.6 g, 34.7 mmol) in tetrahydrofuran (69.4 mL), 6 M hydrochloric acid (138.9 mL) was added, and the obtained solution was stirred at room temperature for 15 hours. The reaction solution was cooled in ice, and 50% aqueous sodium hydroxide solution was added dropwise thereto at 0° C. until it became basic. Thereafter, the resulting solution was extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by recrystallization (n-hexane/ethyl acetate, 70° C.) to obtain the title compound (10.5 g, 27.9 mmol, 80%) as a white solid.
