Procedure

[(2R)-3-(2-{2-Chloro-5-fluoro-6-[(4-methyl-1-piperazinyl)(1,3-thiazol-2-ylmethyl)amino]-4-pyrimidinyl}hydrazino)-2-(cyclopentylmethyl)-3-oxopropyl](tetrahydro-2H-pyran-2-yloxy)formamide (0.1688 g, 0.258 mmol) was taken up in water (2 mL) and acetic acid (8 mL). The reaction was left to stir overnight. Purification by RP-HPLC provided [(2R)-3-(2-{2-chloro-5-fluoro-6-[(4-methyl-1-piperazinyl)(1,3-thiazol-2-ylmethyl)amino]-4-pyrimidinyl}hydrazino)-2-(cyclopentylmethyl)-3-oxopropyl]hydroxyformamide as a beige solid (0.0483 g, 25%). LCMS: (M+H)+=571.2.
