1,1-Dimethylethyl (2S)-2-({[2-chloro-5-(dihydroxyamino)-4-pyrimidinyl]amino}methyl)-1-pyrrolidinecarboxylate (2.064 g, 5.74 mmol) was dissolved in MeOH (40 mL), degassed and placed under argon. 10% Pd/C (619 mg) was added, and the contents were thoroughly degassed and placed under a hydrogen balloon for 2 h. The contents were then degassed, and the Pd/C was removed by filtration through a fiberglass filter, washing with MeOH. The filtrate was concentrated in vacuo to provide pure 1,1-dimethylethyl (2S)-2-{[(5-amino-4-pyrimidinyl)amino]methyl}-1-pyrrolidinecarboxylate (1.589 g, 94%). LCMS: (M+H)+: 294.1.
