Hydrochloric Acid → 5-({[(4-bromo-2,6-dichlorophenyl)sulfonyl](methyl)amino}methyl)-N-{2-[4-(4,5-dihydro-1H-imidazol-2-yl)phenyl]ethyl}-N-methylfuran-3-carboxamide

참여 물질

반응 단계

To a stirred solution of 5-({[(4-bromo-2,6-dichlorophenyl)sulfonyl](methyl)amino}methyl)furan-3-carboxylic acid (54 mg, 0.12 mmol), EDCI (29 mg, 0.15 mmol) and HOBt (20 mg, 0.15 mmol) in DMF (3 mL) was added a solution of 2-[4-(4,5-dihydro-1H-imidazol-2-yl)phenyl]-N-methylethanamine.HCl (29 mg, 0.11 mmol) and DIPEA (0.084 mL, 0.48 mmol) in DMF (2 mL). The reaction was stirred at ambient temperature for 18 h, then diluted with EtOAc. The solution was washed with water, saturated aqueous NaHCO3 and 1:1 saturated brine:water. The organic extracts were dried over MgSO4, and solvent was removed in vacuo. A portion of the crude product was purified using prep method C.
