Participants

Reaction Steps

The obtained 3-[2-(2-hydroxy-4-chlorophenyl)-5-isopropyl-4-oxazolyl]-1-(3-methyl-4-hydroxyphenyl)propan-1-one (378 mg, 0.95 mmol) was dissolved in acetone (20 mL). To the solution, potassium carbonate (158 mg, 0.95 mmol) and ethyl bromoacetate (158 mg, 0.95 mmol) were added while cooling with ice. The mixture was allowed to room temperature, and stirred for 20 hours. After insoluble was filtered off, the mixture was washed with acetone to remove the solvent. The residue was purified by column chromatography on silica gel with hexane/ethyl acetate (4/1) to give the desired compound (315 mg) as white solid (yield 69%).
