実験手順

4-Chloro-6,7-bis-(2-methoxy-ethoxy)-quinazoline (153 mg, 0.49 mmol), pyridine (40 μL) and 3-ethynyl-6-methylaniline (71 mg, 0.54 mmol) were reacted in DMF (3 mL) at 110° C. under an atmosphere of N2 for 36 hours. The solvent was removed in vacuo and the residue was partitioned between CHCl3 and saturated aqueous NaHCO3. The organic extracts were washed with brine, dried over Na2SO4, filtered and concentrated in vacuo. The crude product was chromatographed on silica using 40% acetone/CH2Cl2 to provide 40 mg (19%) of pure product as its free base. This oil was dissolved in a minimum volume of CHCl3, diluted with several volumes of ether, and triturated with 1M HCl in ether to precipitate the title product as a white solid (M.P. 170°-185° C. (dec); LC-MS: 408 (MH+); anal. RP18-HPLC RT: 3.93 min.).
