Participants

Reaction Steps

The compound (52.9 mg) obtained in Example 19-3 was dissolved in anhydrous chloroform (2.0 ml). The solution was added with triethylamine (0.054 ml) and then added with methanesulfonyl chloride (manufactured by Kanto Kagaku) (0.027 ml), followed by stirring at room temperature for 17 hours. After completion of the reaction, chloroform (3.0 ml) was added to the solution, and the whole was washed with water. The organic layer was dried with anhydrous magnesium sulfate. Subsequently, the solvent was distilled off and the residue was then purified through silica gel column chromatography (manufactured by Fuji Silysia Chemical Ltd.) (hexane/ethyl acetate), thereby obtaining the subject compound (31.7 mg) as a white solid.
