Versuchsvorschrift
To a solution of 2-isobutylthiazole (600 mg, 4.25 mmol) in DMF (2 mL) was added N-bromosuccinimide (1.134 g, 6.37 mmol). The mixture was stirred at room temperature for 3 hours then subjected to flash column chromatography using 10% ethyl acetate/hexane to give a yellow oil (815.2 mg, 87% yield). LCMS (Conditions C): Tr 3.51 min; (M+H)+: 219.90 (100%), 221.90 (100%).
