실험 절차

To a solution of N-(2-hydroxy-5-nitrophenyl)butyramide (Compound 117, 1.75 g, 7.8 mmol) in CH2Cl2 (40 ml) at 0° C. was added Et3N (1.4 ml, 10.1 mmol) and Tf2O (1.7 ml, 10.2 mmol). After 10 min, the reaction was diluted with CH2Cl2, washed with H2O and brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified by chromatography on silica gel (0→25% EtOAc-hexanes) to yield the title compound.
