Versuchsvorschrift

A mixture of 5-methyl-2-phenyl-thiazole-4-carboxylic acid ethyl ester (7.76 g, 0.03 mol), N-bromosuccinimide (5.87 g, 0.03 mol) and benzoyl peroxide (761 mg, 3.30 mmol) in carbon tetrachloride (130 mL) was refluxed for 16 h before it was cooled to room temperature and partitioned between dichloromethane and water. The organic layer was washed with saturated aqueous sodium bicarbonate solution, brine, dried over anhydrous sodium sulfate and concentrated in vacuo to give the title compound as a yellow oil (10.66 g); MS: (+) m/z 325.93, 328.00 (M+1, 79Br/81Br).
