실험 절차

4-(6-Bromo-4-methyl-3-oxo-3,4-dihydro-pyrazin-2-ylamino)-2-nitro-benzoic acid (3) (1.0 g, 2.72 mmol), (benzotriazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate [BOP] (120 mg, 2.72 mmol,), diisopropylethylamine (1.42 mL, 8.15 mmol) and 2-methylaminoethanol (0.33 mL, 4.07 mmol) are dissolved in DMF (25 mL) at room temperature and allowed to react for 60 min. The reaction is quenched by the addition of water (120 mL) and the resulting suspension was allowed to stir for 15 min. The suspension is then filtered, washed with water (3×50 mL) and then air-dried to give 4-(6-bromo-4-methyl-3-oxo-3,4-dihydro-pyrazin-2-ylamino)-N-(2-hydroxy-ethyl)-N-methyl-2-nitro-benzamide (4) as a yellow solid (1.05 g).
