Reaction Steps

A flask was charged with 5-bromo-2-(4-phenethylthiazol-2-ylamino)pyridine-4-thiol (0.040 g, 0.10 mmol), 3,5-dichloroisonicotinonitrile (0.019 g, 0.11 mmol), Cs2CO3 (0.037 g, 0.11 mmol), and DMSO (2 mL). The reaction mixture was stirred at ambient temperature overnight, then quenched with water, extracted with EtOAc, dried, and concentrated. The crude material was purified by flash chromatography to provide the desired product (0.026 g, 48% yield) as a yellow solid. 1H NMR (CDCl3) δ 8.74 (d, 2H), 8.39 (s, 1H), 7.16-7.30 (m, 5H), 6.68 (s, 1H), 6.33 (s, 1H), 2.85-2.92 (m, 4H).
