[(2R)-2-(cyclopentylmethyl)-3-(2-{5-fluoro-2-methyl-6-[(3S)-3-methyl-4-morpholinyl]-4-pyrimidinyl}hydrazino)-3-oxopropyl][(phenylmethyl)oxy]formamide → [(2R)-2-(cyclopentylmethyl)-3-(2-{5-fluoro-2-methyl-6-[(3S)-3-methyl-4-morpholinyl]-4-pyrimidinyl}hydrazino)-3-oxopropyl]hydroxyformamide

Participants

Reaction Steps

To a solution of [(2R)-2-(cyclopentylmethyl)-3-(2-{5-fluoro-2-methyl-6-[(3S)-3-methyl-4-morpholinyl]-4-pyrimidinyl}hydrazino)-3-oxopropyl][(phenylmethyl)oxy]formamide (309.1 mg, 0.563 mmol) in methanol (6 mL) was added 20% Pd(OH)2/C (50% water, 62 mg). The suspension was hydrogenated for 1 h and then filtered through a PTFE membrane. The resulting solution was concentrated in vacuo and purified by Gilson RPLC to give [(2R)-2-(cyclopentylmethyl)-3-(2-{5-fluoro-2-methyl-6-[(3S)-3-methyl-4-morpholinyl]-4-pyrimidinyl}hydrazino)-3-oxopropyl]hydroxyformamide (94.0 mg, 36%) as a white solid following crystallization from EtOAc-Et2O. LCMS: (M+H)+: 459.1.
