실험 절차
To a flask containing 7-Bromo-3-chloroisoquinoline (1.5 g, 6.19 mmol) was added NIS (1.4 g, 6.9 mmol). The flask was placed in an ice bath and treated with TfOH (40 mL) and stirred at RT overnight. The reaction mixture was carefully poured into ice, and the aqueous layer was extracted with DCM. The combined extracts were washed with brine, dried over Na2SO4, and concentrated under reduced pressure. The crude residue was purified by silica gel column chromatography (Hexanes:DCM→1:1) to provide the title product.
