Trifluoroacetic acid → 2-(2-Hydroxy-5-(tetrahydrofuran-3-yl)benzamido)-4-phenylbenzoic acid

Participants

Reaction Steps

Trifluoroacetic acid (2 mL) was added to a methylene chloride (5 mL) solution of the obtained tert-butyl 2-(2-hydroxy-5-(tetrahydrofuran-3-yl)benzamido)-4-phenylbenzoate (0.027 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 0.023 g of 2-(2-hydroxy-5-(tetrahydrofuran-3-yl)benzamido)-4-phenylbenzoic acid as a white solid.
