Participants

Reaction Steps

5 N hydrochloric acid (15 ml) was added to a THF (15 ml) solution of the compound 321-9 (1.01 g), and the obtained mixture was stirred at room temperature for 2 hours. A 5 N sodium hydroxide aqueous solution was added to the reaction solution under cooling on ice for neutralization, and the mixture was then extracted with ethyl acetate. The obtained organic layer was washed with a saturated sodium chloride aqueous solution, then dried over magnesium sulfate, and concentrated under reduced pressure. The obtained residue was washed with ethyl acetate and collected by filtration, so as to obtain the title compound 321 (721 mg).
