Reaction Steps

mL 5-Bromo-3-(phenylthio)pyridin-2-amine (1.0 g, 3.6 mmol), 2-chloro-3-isothiocyanatopyridine (0.61 g, 3.6 mmol), DMF (2 mL) were heated to 90° C. for 8 hours. Cooled to ambient temperature and the solids were diluted with mL CH2Cl2 (2 mL) and filtered and washed with small amount of CH2Cl2 to afford the title compound (0.98 g, 61% yield). 1H NMR (d6-DMSO) δ 8.50 (d, 1H), 8.39 (dd, 1H), 7.98 (s, 1H), 7.92 (dd, 1 h), 7.38-7.25 (m, 6H). Mass spectrum (apci) m/z=414.8 (M+H).
