Procedure

5-chloro-3-phenoxypyridin-2-amine (8.493 g, 38.490 mmol) and benzoyl isothiocyanate (6.9096 g, 42.339 mmol) were placed in THF (200 mL) and stirred at room temperature for 2 hours. THF was removed. A suspension was made by adding Hexanes:EtOAc (9:1). The suspension was filtered and the solid was washed with hexanes then dried to afford the title compound (13.752 g, 93.1% yield) as a yellow solid. 1H NMR (d6-DMSO) δ 12.35 (s, 1H), 11.84 (s, 1H), 8.34 (d, 1H), 7.95 (d, 2H), 7.66 (t, 1H), 7.53 (t, 2H), 7.44 (m, 3H), 7.24 (t, 1H), 7.18 (m, 2H); Mass spectrum (apci) m/z=383.1 (M+H).
