Reaction Steps

Compound 22-6 (310 mg) was dissolved in dichloromethane (30 ml) and cooled to 0° C. To the solution were added triethylamine (430 μl) and methanesulfonyl chloride (210 μl) successively through an injector, followed by stirring at room temperature for 24 hours. The resulting mixture was diluted with 1 N aqueous hydrochloric acid, and an organic layer was dried over magnesium sulfate and filtered. The filtrate was concentrated under reduced pressure and the obtained residue was purified by column-chromatography (ethyl aceate/hexane=1/1) to yield the compound 22-7 (400 mg, 78.5%)
