Reaction Steps

(R)-1-(4-Guanidino-phenyl)-pyrrolidine-2-carboxylic acid cyclopropylamide (Method 63; 0.29 g, 1.0 mmol) and ((2E)-3-(dimethylamino)-1-(1-isopropyl-2-methyl-1H-imidazol-5-yl)prop-2-en-1-one, (Method 24 of WO 03/076436; 0.15 g, 0.68 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 (110 mg, 36%). NMR (299.954 MHz, CDCl3) 8.28 (d, 1H), 7.39 (d, 1H), 7.34 (s, 1H), 6.85-6.82 (m, 2H), 6.60-6.57 (m, 3H), 5.61 (septet, 1H), 3.96-3.92 (m, 1H), 3.62 (t, 1H), 3.19 (q, 1H), 2.76-2.67 (m, 1H), 2.56 (s, 3H), 2.30-2.22 (m, 2H), 2.07-1.84 (m, 2H), 1.47 (d, 6H), 0.78-0.70 (m, 2H), 0.45-0.38 (m, 2H); m/z 446.
