To a solution of racemic 1-(5-fluoro-6-hydrazino-2-methyl-4-pyrimidinyl)-N,N,4,4-tetramethyl-3-pyrrolidinamine (0.0617 g, 0.219 mmol) in DMF (3 mL) was added (2R)-3-cyclopentyl-2-({formyl[(phenylmethyl)oxy]amino}methyl)propanoic acid (0.0637 g, 0.209 mmol), N-methylmorpholine (0.120 mL, 1.091 mmol), 1-hydroxy-7-azabenzotriazole (34 mg, 0.250 mmol), and EDC (48 mg, 0.250 mmol). The solution was stirred overnight and then purified directly by Gilson RPLC to give [(2R)-2-(cyclopentylmethyl)-3-(2-{6-[4-(dimethylamino)-3,3-dimethyl-1-pyrrolidinyl]-5-fluoro-2-methyl-4-pyrimidinyl}hydrazino)-3-oxopropyl][(phenylmethyl)oxy]formamide (0.0775 g, 65% yield, mixture of diastereomers) as a pale yellow oil. LCMS: (M+H)+: 570.3.
