실험 절차

The mixture of 2-ethanoyloxy-5-tert-butoxycarbonylaminobenzoic acid (1.01 g, 3.42 mmole) in TFA/CH2Cl2 (20.0 ml. 1:1 v/v) was stirred for 30 min at room temperature. After the reaction mixture was concentrated, the residue was dissolved in ether. The resulting residue was recrystallized from ethyl acetate/hexane to give 0.65 g (97% yield) of 2-ethanoyloxy-5-aminobenzoic acid as a white solid.
