실험 절차
To a solution of 5-ethoxypyrimidine (2.00 g, 16.1 mmol) in CH2Cl2 (100 mL) was added 3-chloroperoxybenzoic acid, 50-60% tech. grade, (6.13 g, 17.7 mmol) and the reaction stirred at 23° C. for 18 h. The reaction was extracted with water (2 mL) containing Na2CO3 (1.71 g, 16.1 mmol). The organic phase was dried with anhydrous K2CO3, filtered, and concentrated under reduced pressure to afford the N-oxide (1.75 g, 78%).
