실험 절차

To 6-bromo-2-naphthamide (1 g, 4.00 mmol) in dioxane (8.00 ml) at 0° C. was added pyridine (0.647 ml, 8.00 mmol) and then TFAA (0.621 ml, 4.40 mmol) dropwise. The reaction was stirred at room temperature for 3 h. The mixture was quenched with H2O and extracted with EtOAc two times, dried over magnesium sulfate, filtered, concentrated. The title compound (653 mg, 70%) was isolated as a beige solid, and used as is for the next step.
