실험 절차

The 3-bromo-4-(methyloxy)benzoic acid (commercial: ICN) (243 mg, 1.05 mmol) stirring in DMF (10 ml) was treated with EDC (219 mg, 0.1.14 mmol) followed by HOBt (156 mg, 0.1.14 mmol). The resultant solution was stirred for 10 minutes. Added ethyl 3-{3-chloro-5-[(hydroxyamino)(imino)methyl]-1H-indol-1-yl}propanoate (D96) (324 mg, 1.05 mmol) and stirred at RT for 45 minutes. The solution was heated at 80° C. for 4 hours then left standing overnight. The solution was heated at 80° C. for a further 4 hours to give one major product. Evaporated off the DMF, added EtOAc (50 ml) and washed with water (50 ml). The EtOAc was washed with sat. aqueous sodium hydrogen carbonate (50 ml) and water (50 ml) then dried over MgSO4. Evaporated off the solvent and crystallised from ethanol to yield the title compound as 280 mg of cream solid. δH (400 MHz, d6-DMSO) 1.10 (3H, t), 2.90 (2H, t), 3.99-4.05 (5H, m), 4.49 (2H, t), 7.38 (1H, d), 7.74 (1H, s), 7.80 (1H, d), 7.97 (1H, d), 8.21-8.23 (2H, m), 8.36 (1H, d). MS (ES) C22H1981Br35ClN3O4 requires 505; found 506 (MH+).
