Ethyl bromoacetate → HCID 90022701, compound

Participants

Reaction Steps

To a mixture of 5-chloro-2-hydroxy-N-[2-(2-isopropyl-thiazol-4-yl)-ethyl]-benzamide (400 mg, 1.23 mmol, 1.00 eq.) and potassium carbonate anhydrous (340 mg, 2.46 mmol, 2.00 eq.) in acetone (20 mL), ethyl bromoacetate (0.14 mL, 1.29 mmol, 1.05 eq.) was added. The mixture was stirred at r.t. for 5 hours. The reaction mixture was poured in water (50 mL). The mixture was extracted with AcOEt (2×20 mL). The comb. org. phases were dried over MgSO4 and concentrated in vacuo. The residue was purified by flashmaster (column: 25 g, flow: 30 mL/min, 45 fractions of 15 mL, Heptane+20% AcOEt to Heptane+80% AcOEt) to yield the ester as a white solid.
