1-Benzyl 2,3-di-tert-butyl pyrazolidine-1,2,3-tricarboxylate (14.15 g, 34.8 mmol) was dissolved in dichloromethane (68.6 ml) under N2 at room temperature. TFA (80 ml, 1045 mmol) and water (9.41 ml, 522 mmol) were then added in one portion. The reaction was stirred at 25° C. for 2 days. The solvent was then removed under reduced pressure to give 1-{[(phenylmethyl)oxy]carbonyl}-3-pyrazolidinecarboxylic acid (8.72 g, 34.8 mmol, 100% yield).
