Procedure

300 mg of 4-[(3-chloro-4-fluorophenyl)amino]-6-cyclopropylmethoxy-7-(2-bromoethoxy)-quinazoline and 400 mg of 4-methylamino-dihydro-furan-2-one in 20 ml acetonitrile are combined with 240 mg of potassium carbonate and 70 mg of sodium iodide and refluxed for 24 hours. After cooling to ambient temperature the reaction mixture is filtered and the filtrate is evaporated down in vacuo. The flask residue is chromatographed over a silica gel column with methylene chloride/methanol/concentrated aqueous ammonia solution (97:3:0.05) as eluant. The title compound is obtained as a light beige solid.
