실험 절차

A mixture of 1-chloropropan-2-one (3.827 g, 41.36 mmol), 1-(5-chloro-3-phenoxypyridin-2-yl)thiourea (8.265 g, 29.54 mmol), triethylamine (7.001 mL, 50.23 mmol), and ethanol (30 mL) was refluxed for 3 hours. The ethanol was removed to about one third original volume, and then the reaction mixture was cooled in an ice bath and filtered. The solids were washed with cold ethanol and dried to afford the title compound (8.35 g, 88.96% yield) as a light yellow powder. 1H NMR (d6-DMSO) δ 10.94 (bs, 1H), 8.15 (d, 1H), 7.43 (t, 2H), 7.32 (d, 1H), 7.20 (t, 1H), 7.19 (d, 2H), 6.60 (s, 1H), 2.23 (s, 3H); Mass spectrum (apci) m/z=318.2 (M+H).
