Temperature: 20 °C

Procedure

4-Chloro-6,7-bis-(2-chloro-ethoxy)-quinazoline (600 mg, 1.87 mmol) and 3-ethynyl-aniline (219 mg, 1.87 mmol) were reacted in refluxing isopropanol (15 mL) under an atmosphere of N2 for 2.5 hours. The mixture was cooled to 20° C. and the precipitated product was filtered, washed With isopropanol and ether and dried in vacuo. (707 mg; 86%; M.P. 230°-240° C. (dec); LC-MS: 402 (MH+); anal. RP18-HPLC RT: 5.35 min.).
