The mixture of 1-ethynyl-4-(3-(4-methylpiperazino)propoxy)benzene (230 mg, 0.89 mmol), 2-iodo-N-(methanesulfonyl)aniline (0.89 mmol, 296 mg), Cul (17 mg, 0.089 mmol), Pd(PPh3)2Cl2 (32 mg, 0.045 mmol) and triethylamine (0.5 mL) in DMF (5 mL) was stirred at 80° C. for overnight. After concentration, water (20 mL) was added and extracted by methlene chloride (3×20 mL). The organics was concentrated and purified by column chromatography afforded the title compound (260 mg): 1H NMR (CDCl3, 400 MHz) δ 8.05 (d, 1H, J=8.8 Hz), 7.55 (d, 1H, J=2.1 Hz), 7.50 (td, 2H, J=8.8,2.1 Hz), 7.32 (d, 1H, J=2.1 Hz), 7.30 (d, 1H, J=2.1 Hz), 6.96 (td, 2H J=2.1, 8.8 Hz), 6.60 (d, 1H, J=0.5 Hz), 4.08 (t, 2H, J=6.3 Hz), 2.74 (s, H), 2.55 (m, 10H), 2.33 (s, 3H), 2.02 (quintet, 2H, J=6.3 Hz); EIMS m/z 462 (M+H+).
