Procedure

(2E)-3-(Dimethylamino)-1-(1-isopropyl-2-methyl-1H-imidazol-5-yl)prop-2-en-1-one (Method 24 of WO 03/076436; 140 mg 0.63 mmol) and N-[4-(4-acetylpiperazin-1-yl)phenyl]guanidine bicarbonate salt (Method 2; 240 mg 0.74 mmol) in 2-methoxyethanol (4 ml) were reacted under nitrogen under microwave conditions at 200° C. for 30 minutes. After evaporation under reduced pressure, chromatography on silica gel with MeOH:DCM (2:98 to 6:94) gave the title compound, after ether trituration, as a yellow solid. (85 mg 31.5%). NMR: 1.39 (d, 6H), 2.02 (s, 3H), 2.45 (s, 3H), 3.00 (b t, 2H), 3.06 (b t, 2H), 3.56 (b q, 4H), 5.70 (septuplet, 1H), 6.91 (d, 2H), 6.95 (d, 1H), 7.38 (s, 1H), 7.46 (d, 2H), 8.31 (d, 1H), 9.15 (s, 1H); m/z 420.
