Reaction Steps

[(2R)-3-(2-{2-chloro-5-fluoro-6-[(1S,4S)-5-methyl-2,5-diazabicyclo[2.2.1]hept-2-yl]-4-pyrimidinyl}hydrazino)-2-(cyclopentylmethyl)-3-oxopropyl][(phenylmethyl)oxy]formamide (90 mg, 0.18 mmol) was dissolved in 3 mL of MeOH, degassed and placed under argon. 10% Pd/C (18 mg) was added, and the contents were thoroughly degassed and placed under a hydrogen balloon for approximately 3 hrs. The contents were then degassed and filtered through Celite, and the Celite pad was washed with DCM and MeOH. The resulting filtrate was concentrated in vacuo to provide the pure [(2R)-3-(2-{2-chloro-5-fluoro-6-[(1S,4S)-5-methyl-2,5-diazabicyclo[2.2.1]hept-2-yl]-4-pyrimidinyl}hydrazino)-2-(cyclopentylmethyl)-3-oxopropyl]hydroxyformamide (42 mg, 57%). LCMS: (M+H)+: 429.4.
