Participants

Reaction Steps

The obtained 7-allyl-6-hydroxy-3-[2-[2-(2,4-dichlorophenyl)-5-isopropyl-4-oxazolyl]ethyl]-1,2-benzisoxazole (45 mg, 0.098 mmol) and potassium carbonate (20 mg, 0.147 mmol) was suspended in acetone (5.0 mL). An acetone solution of ethyl bromoacetate (25 mg, 0.147 mmol) was added to the suspension while cooling with ice. The mixture was allowed to room temperature, and stirred for 20 hours. After insoluble was filtered off, the filter cake was washed with acetone. The filtrate and washings were combined, and concentrated. The residue was purified by column chromatography on silica gel with hexane/ethyl acetate (4/1) to give the desired compound (43 mg) as colorless oil (yield 80%).
