Reaction Conditions

Reaction Steps

Compound 8-1 (1 g) was dissolved in anhydrous dichloromethane and the solution was cooled to 0° C. To the solution was added triethylamine (630 μl) and methanesulfonyl chloride (350 μl) in order and the mixture was stirred at room temperature for 24 hours. After confirming the completion of the reaction using TLC, the resulting mixture was neutralized with hydrochloric acid solution, diluted with water, and then extracted three times with dichloromethane. The extracted organic layer was washed with water and saturated aqueous sodium chloride solution, dried over magnesium sulfate, and then dried under reduced pressure. The obtained residue was purified by column-chromatography (hexane/ethyl acetate=2/1) to yield the compound 8-2 (1.28 g, 95%) as a white solid.
