Participants

Reaction Conditions

Reaction Steps

Methanesulfonic acid (81.6 μL) and ethanol (10 mL) were added to Compound 9 (500 mg), and the mixture was heated for dissolution (external temperature: 70° C.). The solution was returned to room temperature, followed by stirring overnight. The precipitated crystals were recovered through filtration, and the recovered crystals were washed sequentially with a small amount of ethanol and hexane. The crystals were thoroughly dried, to thereby yield the target product (yield: 530 mg, 85%).
