Trifluoroacetic acid → HCID 58508914, compound

Participants

Reaction Steps

Thioanisole (0.82 mL) and trifluoroacetic acid (2.6 mL) were added to the obtained tert-butyl 2-(2-(benzyloxy)-4-(furan-3-yl)benzamido)-4-phenylbenzoate (0.076 g), followed by stirring at room temperature for 3 hours and 20 minutes. The solvent was evaporated under reduced pressure, and a 2 mol/L aqueous solution of sodium hydroxide and toluene were added to the residue. The aqueous layer was separated and adjusted to a pH of 4.5 with 6 mol/L hydrochloric acid. The solid substance was collected by filtration to obtain 0.016 g of 2-(4-(furan-3-yl)-2-hydroxybenzamido)-4-phenylbenzoic acid as a brown solid.
