Yield:102074-24-8 87%

Reaction Conditions:

with 3-chloro-benzenecarboperoxoic acid in dichloromethane at 10 - 20; for 22 h;

Steps:

4.1 Step 1: Synthesis of 3-ethoxypyridine 1-oxide

3-ethoxypyridine (1.683 g, 13.67 mmol) was dissolved in DCM (32.5 mL), and then m-chloroperoxybenzoic acid (3.07 g, 17.77 mmol) was added at 10° C. and stirred at room temperature for 22 hours. Sodium thiosulfate was added and stirred at 15° C. for 3 hours. After the reaction was completed, it was extracted with DCM. The solvent was removed under reduced pressure and purified by column chromatography to obtain the desired product (yield 87%).
