Reaction Steps

1-{[4-(Chloromethyl)-1,3-thiazol-2-yl]methyl}-4-methylpiperazine hydrochloride (0.067 g, 0.238 mmol) and 4-[(3,4-dichlorophenyl)amino]-6-(methoxy)quinazolin-7-ol (0.080 g, 0.238 mmol) were suspended in DMF (4 mL) and potassium carbonate (0.164 g, 1.19 mmol) was added. The mixture was stirred at 70° C. for 21 h. The reaction mixture was concentrated in vacuo and the residue was purified by reverse phase HPLC to afford the title compound as a colorless solid (0.025 g, 0.046 mmol, 19% yield). 1H NMR (400 MHz; CDCl3): 2.08 (s, 5H); 2.39 (s, 3H); 2.59-2.74 (m, 6H); 3.44-3.78 (m, 5H); 3.86 (s, 2H); 3.98 (s, 3H); 5.30 (s, 2H); 7.10 (s, 1H); 7.33 (s, 1H); 7.37 (s, 1H); 7.43 (d, 1H); 7.61 (dd, 1H); 7.99 (d, 1H); 8.60 (s, 1H); MS (EI) for C25H26Cl2N6O2S: 545 (MH+).
