Trifluoroacetic acid → (+/-)-Cyclopentyl{4-[(5,6-difluoro-1-oxo-1,3-dihydro-2H-isoindol-2-yl)methyl]phenyl}acetic acid

Participants

Reaction Steps

27.0 mg (0.06 mmol) of tert-butyl(+/−)-cyclopentyl{4-[(5,6-difluoro-1-oxo-1,3-dihydro-2H-isoindol-2-yl)methyl]phenyl}acetate were initially charged in 200 μl of dichloromethane, and 94 μl of trifluoroacetic acid were added. The mixture was stirred at RT for 2 h. The reaction mixture was then concentrated on a rotary evaporator, and the residue was dried under high vacuum. This gave 23.5 mg (99.7% of theory) of the target compound.
