Trifluoroacetic acid → 2-(2-Hydroxy-5-phenoxybenzamido)-4-phenylbenzoic acid

Participants

Reaction Steps

Trifluoroacetic acid (2.0 mL) was added to the obtained tert-butyl 2-(2-hydroxy-5-phenoxybenzamido)-4-phenylbenzoate (0.017 g), followed by stirring at room temperature for 3 hours. The solvent was evaporated under reduced pressure, and diisopropyl ether was added to the obtained residue. The solid substance was collected by filtration to obtain 0.012 g of 2-(2-hydroxy-5-phenoxybenzamido)-4-phenylbenzoic acid as a white solid.
