반응 단계
3-fluorobenzohydrazide (80.77 mg, 0.5240 mmol) was added to a solution of 3-amino-6-[4-(dimethylcarbamoyl)phenyl]pyrazine-2-carboxylic acid (150 mg, 0.5240 mmol), triethylamine (53.02 mg, 73.03 μL, 0.5240 mmol) and TBTU (252.4 mg, 0.7860 mmol) in DMF (3.000 mL) and the resulting solution stirred at RT for 2 hours. The reaction was diluted with EtOAc and water and the layers separated. The aqueous layer was extracted further with EtOAc (2×) and the combined organics washed with water (3×), dried (MgSO4), filtered and concentrated to give the desired product as a yellow solid (172 mg, 78% Yield). MS (ES+) 423.13
