Reaction Steps

5-({[(4-methoxy-2,6-dimethylphenyl)sulfonyl](methyl)amino}methyl)-2-methylfuran-3-carboxylic acid (82 mg, 0.22 mmol) was dissolved in DCE (1 mL) and CDI (72 mg, 0.33 mmol) was added. The reaction was stirred at ambient temperature for 2 h and 0.5 mL of this solution was added to a flask containing 1-[4-(4,5-dihydro-1H-imidazol-2-yl)phenyl]-N-methylmethanamine.3 HCl (31 mg, 0.11 mmol) and DIPEA (0.076 mL, 0.44 mmol) in DMF (2 mL). The reaction was stirred at ambient temperature for 3 days, then heated in a microwave at 120° C., 250 psi, 200 W for 2×20 min. The reaction was concentrated and diluted with DCM, then washed with water and saturated brine, and dried over MgSO4. The filtrate was shaken with Ambersep and PL-MIA resins, then filtered. The solvent was removed in vacuo and a portion of the crude product purified using prep method C.
