반응 단계

A solution of 2-bromoacetylpyridine (1.0 g, 5 mmol) in toluene (5 mL) was treated with 3-bromo-5-iodobenzamide (2.0 g, 6 mmol) and the mixture heated at reflux for 60 hours. The mixture was then cooled and the solvent was removed in vacuo. Silica gel chromatography using a gradient of hexane to ethyl acetate afforded 10 mg (1%) of 2-(3-bromo-5-iodophenyl)-4-(pyridin-2-yl)-1,3-oxazole: 1H-NMR (CDCl3), δ ppm: 8.62 (d, 1H), 8.42 (m, 1H), 8.38 (s, 1H), 8.24 (m, 1H), 8.00 (t, 1H), 7.95 (d, 1H), 7.8 (m, 1H), 7.27 (m, 1H).
