Diiodomethane → HCID 89666888, compound

Participants

Reaction Steps

A methylene chloride (3 ml) solution containing diiodomethane (0.2 ml) and a methylene chloride solution (3 ml) containing 2-((1R,6S)-6-(benzyl ((R)-1-phenylethyl)amino)-3-cyclohexen-1-yl)isoindolin-1,3-dione (0.36 g) obtained in the 1st step were added to a methylene chloride solution (10 ml) containing diethyl zinc (1M in hexane) (2.47 ml), followed by stirring for 15 hours. Methanol and sodium hydrogen carbonate were added to the reaction solution. The reaction solution was filtered through Celite. The filtrate was extracted with ethyl acetate. The organic layers were washed with water and saturated saline and dried over anhydrous sodium sulfate. The solvent was distilled away under reduced pressure and the obtained residue was purified by silica gel chromatography (n-hexane:ethyl acetate=1:0 to 1:0.2). A 2-((3R,4S)-4-(benzyl ((R)-1-phenylethyl)amino)bicyclo[4.1.0]heptan-3-yl)isoindolin-1,3-dione (0.20 g) was thus obtained.
