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

Participants

Reaction Steps

71.0 mg (0.17 mmol) of tert-butyl(+/−)-cyclopentyl{4-[(3-oxo-1,3-dihydro-2H-indazol-2-yl)-methyl]phenyl}acetate were initially charged in 400 μl of dichloromethane, and 134 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 82 mg of crude product, which was used without further purification.
