Procedure
To a solution obtained by adding 1,2-hydrazinedicarboxylic acid bis(2-methoxyethyl) ester (200 mg, 0.85 mmol) and toluene (2 mL) to a 10 mL flask, followed by cooling with an ice bath, was added dropwise a 5% sodium hypochlorite solution (1.39 g, 0.85 mmol), and the reaction was allowed to proceed for one hour. After the reaction, the solution was washed with water (1 mL, ×2), and dehumidified with anhydrous magnesium sulfate, followed by concentration to dryness. The resulting solid was recrystallized with toluene (1 mL) and hexane (5 mL), to give azodicarboxylic acid bis(2-methoxyethyl) ester as a pale yellow crystal (73 mg, yield: 37%).
