実験手順

To the solution of 2-phenyl-4-(pyridin-4-yl)thiazole (70 mg, 0.3 mmol) in CHCl3 was added Na2CO3 (311 mg, 2.9 mmol) and Br2 (75 μL, 1.470 mmol) at rt. After 1 h, additional charges of Na2CO3 (1 g, 9.4 mmol) and Br2 (0.5 mL, 1 mmol) were added and the reaction maintained for another hour. The reaction was diluted with CHCl3 and filtered through a pad of Celite, washing the filter cake thoroughly with CHCl3. The combined filtrates were concentrated of provide 0.5-bromo-2-phenyl-4-(pyridin-4-yl)thiazole which was carried forward without further purification: LCMS (m/z): 318.9 (MH+), tR=0.75 min.
