실험 절차
At room temperature, 1.50 g of 2H-1,3-oxazine-2,6(3H)-dione, 2.19 g of potassium carbonate and 3.77 g of methyl iodide were sequentially added to 30 ml of acetone, and the mixture was stirred for 10 hours under heat refluxing condition. The reaction mixture was cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure, and the resulting solid was dried to obtain 1.46 g of 3-methyl-2H-1,3-oxazine-2,6(3H)-dione represented by the formula:
