Versuchsvorschrift

To a stirred solution of 5-({[(4-bromo-2,6-dichlorophenyl)sulfonyl](methyl)amino}methyl)furan-3-carboxylic acid (60 mg, 0.14 mmol), EDCI (33 mg, 0.17 mmol) and HOAt (23 mg, 0.17 mmol) in DMF (0.5 mL) was added a solution of 1-[4-(4,5-dihydro-1H-imidazol-2-yl)phenyl]-N-methylmethanamine.HCl (28 mg, 0.13 mmol) and DIPEA (0.025 mL, 0.14 mmol) in DMF (0.5 mL). The reaction was heated to 60° C. for 5 h, then concentrated and diluted with DCM. The solution was washed with saturated aqueous NH4Cl(2×2 mL) and saturated brine (2 mL), and dried over MgSO4. The filtrate was shaken with Ambersep resin for 48 h, then filtered. The solvent was removed in vacuo and a portion of the crude product purified using prep method C.
