with N-Bromosuccinimide in N,N-dimethyl-formamide at 20; for 3 h;

Steps:

191.1

To a solution of 2-isopropoxythiazole (300 mg, 2.32 mmol) in DMF (2 niL) was added N-bromosuccinimide (620 mg, 3.48 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 colorless oil (440 mg, 91% yield).
