실험 절차

Para-nitrobenzyliminodiacetic acid (1.g, 3.08 nmoles) and Milli-Q® water (55 ml) were combined. The pH of the resultant solution was adjusted to 11.5 by the addition of 10 N NaOH solution. Palladium catalyst (5% palladium on carbon, 700 mg) was added under a hydrogen atmosphere. The reaction mixture was stirred for approximately 6 hours and then filtered through glass sinters and a 0.45 micron Millex filter. The pH of the filtrate was adjusted to below 2 with 1 N HCl and then taken to dryness in vacuo. The residue was dissolved in Milli-Q® water (10 ml) and stored at -70° C. in 1 ml aliquots until further use. Nuclear magnetic resonance confirmed the structure (300 mHz, CDCl3) δ3.268(4H), 3.591(2H); 4.321(2H), 4.741(solvent); 6.822-6.850 (2H); 7.142-7.170 (2H). 13Carbon confirms the structure, δ45.09(1C); 61.05(1 C); 61.153(2C); 119.389 (2C); 131.295 (2C); 131.568 (1C); 148.104 (1C), 176.7 (1C); 181.843 (2C).
