Reaction Steps

6-{[(2-Amino-1,3-thiazol-4-yl)methyl]amino}-5-fluoro-4-hydrazino-2-methylpyrimidine (125 mg, 0.44 mmol), (2R)-3-cyclopentyl-2-{[formyl(tetrahydro-2H-pyran-2-yloxy)amino]methyl}propanoic acid (130 mg, 0.44 mmol), and HOAt (65 mg, 0.48 mmol) were dissolved in 4 mL of DMF. NMM (0.15 mL, 1.32 mmol) was added, followed by EDC (96 mg, 0.48 mmol). After stirring overnight at room temperature, the reaction mixture was purified by RP-HPLC to provide [(2R)-3-[2-(6-{[(2-amino-1,3-thiazol-4-yl)methyl]amino}-5-fluoro-2-methyl-4-pyrimidinyl)hydrazino]-2-(cyclopentylmethyl)-3-oxopropyl](tetrahydro-2H-pyran-2-yloxy)formamide (114 mg, 46%). LCMS: (M+H)+: 565.3.
