The solution from 2-acetoxybenzoic acid 2,2-dimethyl-[1,3]dioxolan-4-yl-methylamide (184 mg, 0.63 mmol) in dichloromethane (5 ml) is treated with trifluoroacetic acid (1 ml). After 0.5 h at room temperature, the mixture is concentrated, the residue is taken up in toluene (10 ml) and the solution is concentrated. The residue is purified by column chromatography (dichloromethane/methanol=10/1). Yield: 132 mg.
