5-({[(4-methoxy-2,6-dimethylphenyl)sulfonyl](methyl)amino}methyl)-2-methylfuran-3-carboxylic acid (100 mg, 0.28 mmol) was dissolved in DMF (2 mL) and EDCI (65 mg, 0.34 mmol) and HOAt (46 mg, 0.34 mmol) were added. 1 mL of this solution was added to a flask containing 1-[4-(4,5-dihydro-1H-imidazol-2-yl)phenyl]ethanamine.HCl (27 mg, 0.13 mmol) and DIPEA (0.024 mL, 0.14 mmol) in DMF (2 mL). The reaction was concentrated and diluted with DCM, then washed with saturated aqueous NH4Cl (2×2 mL) and saturated brine (2 mL), and dried over MgSO4. The filtrate was shaken with Ambersep and PL-MIA resins for 48 h, then filtered. The solvent was removed in vacuo and a portion of the crude product purified using prep method C.
