실험 절차

A solution of 2-bromoacetylpyridine (400 mg, 2.0 mmol) in ethanol (5 mL) was treated with 3-iodothiobenzamide (1.2g, 6 mmol) and the mixture heated at reflux for 16 hours. After cooling the mixture was concentrated in vacuo. Silica gel chromatography of the residue using a gradient of hexane to ethyl acetate afforded 302 mg (55%) of 2-(3-iodophenyl)-4-(pyridin-2-yl)-1,3-thiazole, as a white solid.
