Trifluoroacetic acid → HCID 58136644, compound

Participants

Reaction Steps

90.0 mg (0.20 mmol) of tert-butyl cyclopentyl{4-[(4,7-difluoro-1-hydroxy-3-oxo-1,3-dihydro-2H-isoindol-2-yl)methyl]phenyl}acetate were initially charged in 1 ml of dichloromethane, and 300 μA of trifluoroacetic acid and 62 μl (0.39 mmol) of triethylsilane were added. The mixture was stirred at RT for 2 h. The reaction mixture was then concentrated on a rotary evaporator, the residue was taken up in ethyl acetate and the solution was washed with water and saturated sodium chloride solution. The organic phase was dried over magnesium sulfate and concentrated under reduced pressure. This gave 77.0 mg of the target compound.
