실험 절차

mL 5-Bromo-3-(phenylthio)pyridin-2-amine (17 g, 60.5 mmol), benzoyl isothiocyanate (9.79 mL, 72.6 mmol), and THF (300 mL) was stirred at 40° C. overnight. Concentrated to half of the original volume and 9:1 hexanes:EtOAc (500 mL) was added. Filtered to afford the title compound (25.7 g, 95.7% yield).
