The title compound was prepared from (2Z)-3-(dimethylamino)-2-fluoro-1-(1-isopropyl-2-methyl-1H-imidazol-5-yl)prop-2-en-1-one (Method 14; 335 mg, 1.40 mmol) and N-[4-((2S,5R)-4-acetyl-2,5-dimethylpiperazin-1-yl)phenyl]guanidine (Method 35; 737.1 mg, 2.10 mmol) by the procedure of Example 116. The reaction mixture was evaporated under reduced pressure and the residue purified by chromatography on silica gel with MeOH:DCM:EtOAc (1:49.5:49.5 to 6:47:47) to give a solid which required further purification with MeOH:DCM (1:99 to 6:94). After trituration with ether and evaporation of the solvent, the title compound was obtained as a solid which was dried in vac oven overnight at 50° C. (330 mg, 51%). NMR: (500 MHz) 0.95 (d, 3H), 1.33 (d, 3H), 1.40 (d, 6H), 2.03 (s, 3H), 2.50 (s, 3H+DMSO), 3.17 (m, 2H), 3.43 (brs, 1H), 3.83 (brs, 1H), 4.00 (m, 1H), 4.47 (brs, 1H), 5.40 (septet, 1H), 6.83 (d, 2H), 7.32 (d, 1H), 7.37 (d, 2H), 8.35 (d, 1H), 8.7 (s, 1H); 19F NMR (500 MHz MHz) −149.95 (t, 1F); m/z 466.
