2-Bromo-1-(4-fluorophenyl)ethan-1-one → HCID 28839372, compound

Participants

Reaction Steps

To a stirred solution of ethyl 3-amino-3-thioxopropanoate (20.00 g, 135.9 mmol) in ethanol (120 mL) was added 2-bromo-4′-fluoroacetophenone (29.49 g, 135.9 mmol). The mixture was refluxed for 1 hour, concentrated and partitioned between ethyl acetate (300 mL) and aqueous NaHCO3 (400 mL). The organic layer was combined with a backextract of the aqueous layer (ethyl acetate, 1×100 mL), dried (Na2SO4) and concentrated. The resulting light brown solid was purified by flash chromatography using a hexane/ethyl acetate gradient to afford ethyl 2-(4-(4-fluorophenyl)thiazol-2-yl)acetate as an off-white solid (29.92 g, 83%).
