Potassium Carbonate → 5-Bromo-3-propyl-3H-benzooxazol-2-one

Participants

Reaction Steps

A 100 mL round-bottomed flask was charged with 5-bromo-2-benzoxazolinone (0.750 g, 3.50 mmol), n-propyl iodide (0.684 mL, 7.01 mmol), potassium carbonate (1.211 g, 8.76 mmol) and Dioxane (5 mL). The reaction mixture was stirred at room temperature for overnight. The reaction was quenched with water. Colorless precipitate was collected through filtration and 5-Bromo-3-propyl-3H-benzooxazol-2-one was obtained, ESI-MS: m/z 258.2 (M+H)+
