Reaction Steps

(R)-1-(4-Guanidino-phenyl)-pyrrolidine-2-carboxylic acid cyclopropylamide (Method 63) (0.36 g, 1.25 mmol) and (2Z)-3-(dimethylamino)-2-fluoro-1-(1-isopropyl-2-methyl-1H-imidazol-5-yl)prop-2-en-1-one (Method 14; 0.15 g, 0.63 mmol) were added to 2-methoxyethanol (4 ml) and heated at 200° C. for 2 hours in the microwave. The solvent was removed in vacuo and the gum was carefully chromatographed eluting with DCM, 1% MeOH/DCM, 2% MeOH/DCM and finally 3% MeOH/DCM to yield a yellow solid (180 mg, 62%).
