Participants

Reaction Steps

A solution of 3-ethyl-6-hydroxy-7-propylbenz[4,5]isoxazole (2.00 grams; 9.74 mmol) in dry DMF was treated with dibromopropane (7.17 mL; 38.97 mmol) and cesium carbonate (3.49 grams; 10.71 mmol). The solution was stirred at room temperature for 10 hours, then partioned between isopropyl acetate and pH 4.0 buffer. The organic layer was washed twice with water, dried over magnesium sulfate, filtered and concentrated in vacuo. Silica gel chromatography afforded the title compound (1.74 g).
