Versuchsvorschrift
A 250 mL round-bottomed flask was charged with 1-benzoyl-3-(5-chloro-3-phenoxypyridin-2-yl)thiourea (13.752 g, 35.826 mmol) and THF (100 mL). 3M NaOH (119.42 mL, 358.26 mmol) was added and the reaction mixture was heated to 90° C. for 18 hours. The reaction mixture was cooled to room temperature and concentrated. The resulting solids were filtered, washed with water, and dried to provide the title compound (9.49 g, 94.689% yield) as a yellow solid. 1H NMR (d6-DMSO) δ 9.97 (s, 1H), 9.25 (s, 1H), 8.87 (s, 1H), 8.11 (d, 1H), 7.49 (t, 2H), 7.31 (d, 1H), 7.28 (m, 2H), 7.23 (d, 2H); Mass spectrum (apci) m/z=279.9 (M+H).
