Reaction Steps

4-(2,5-Dihydro-1H-pyrrol-1-yl)-5-fluoro-6-hydrazino-2-methylpyrimidine (142 mg, 0.68 mmol), (2R)-3-cyclopentyl-2-{[formyl(tetrahydro-2H-pyran-2-yloxy)amino]methyl}propanoic acid (242 mg, 0.81 mmol), and HOAt (110 mg, 0.81 mmol) were dissolved in 4 mL of DMF. NMM (370 μL, 3.4 mmol) was added, followed by EDC (155 mg, 0.81 mmol). When the starting materials were consumed, the reaction mixture was purified by RP-HPLC to provide ((2R)-2-(cyclopentylmethyl)-3-{2-[6-(2,5-dihydro-1H-pyrrol-1-yl)-5-fluoro-2-methyl-4-pyrimidinyl]hydrazino}-3-oxopropyl)(tetrahydro-2H-pyran-2-yloxy)formamide (140 mg, 55%).
