Participants

Reaction Steps

To a solution of 2-(biphenyl-4-yl)thiazole (540 mg, 2.28 mmol) in anhydrous acetonitrile (10 mL) was added a solution of N-bromosuccinimide in anhydrous acetonitrile (10 mL). The reaction was stirred for 20 h at room temperature. Subsequently, an aqueous solution of Na2SO3 10% (10 ml) was added and the mixture was stirred for 10 minutes. Then, extracted with ethyl acetate (4×25 mL) and the organic layers were washed with an aqueous saturated solution of NaCl (4×50 ml), dried over Na2SO4, filtered and evaporated under reduced pressure. Flash chromatography of the residue on silica gel (SiO2, hexane:ethyl acetate, 9:1) afforded 500 mg of 2-(biphenyl-4-yl)-5-bromothiazole as a white solid (69% yield). EM (IE): m/z (%): 317; (M+, 100), 315; (M+, 95), 316; (M+, 17.1). HRMS (ESI): (M+H)+: calculated for C15H10BrNS: 315.9717. found: 315.9786.
