Sodium Chloride → HCID 67282069, compound

Participants

Reaction Steps

Triethylamine (5.95 ml) and methanesulfonyl chloride (2.42 ml) were added to a dichloromethane (60 ml) solution of the compound 324-2 (5.23 g), while the solution was stirred under cooling on ice. The obtained mixture was stirred at room temperature for 1 hour. A saturated sodium chloride aqueous solution was added to the reaction solution, and the mixture was extracted with ethyl acetate. The obtained organic layer was dried over magnesium sulfate and then concentrated under reduced pressure. The obtained residue was dissolved in dimethyl sulfoxide (30 ml). Sodium cyanide (2.09 g) and sodium iodide (851 mg) were added to the solution, and the obtained mixture was stirred at 90° C. for 3 hours. The temperature of the reaction solution was returned to room temperature. Thereafter, water was added to the reaction solution, and the mixture was extracted with diethyl ether. The obtained organic layer was dried over magnesium sulfate and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (n-heptane:ethyl acetate=1:0 to 4:1), so as to obtain the title compound (4.33 g).
