Reaction Steps
In methyl ethyl ketone (10 mL), 3-[2-(2-hydroxy-4-chlorophenyl)-5-isopropyl-4-oxazolyl]-1-(3-methyl-4-hydroxyphenyl)propan-1-one (150 mg, 0.38 mmol), ethyl 2-bromo-2-methylpropionate (146 mg, 0.75 mmol) and potassium carbonate (103 mg, 0.75 mmol) were suspended. The suspension was refluxed for 20 hours, and allowed to room temperature. After insoluble was filtered off, the mixture was washed with methyl ethyl ketone to removed the solvent. The residue was purified by column chromatography on silica gel with hexane/ethyl acetate (8/1) to give the desired compound (83 mg) as colorless oil (yield 43%).
