Water → tert-butyl(+/-)-cyclopentyl{4-[(5,6-difluoro-1-oxo-1,3-dihydro-2H-isoindol-2-yl)methyl]phenyl}acetate

Participants

Reaction Steps

At 0° C., 60 mg (0.355 mmol) of 5,6-difluoro-2,3-dihydro-1H-isoindol-1-one were added to 21.3 mg (0.53 mmol, 60% pure) of sodium hydride in 1 ml of DMF. The mixture was stirred for 30 min, and 125.3 mg (0.35 mmol) of tert-butyl(+/−)-[4-(bromomethyl)phenyl](cyclopentyl)acetate were then added at 0° C. The reaction mixture was stirred for a further 2 h, and water and ethyl acetate were then added. The organic phase was washed with saturated sodium chloride solution and dried over magnesium sulfate. The crude product was purified by chromatography on silica gel (mobile phase cyclohexane/ethyl acetate 10:1 to 2:1). This gave 30.0 mg (19.2% of theory) of the target compound.
