Procedure

A suspension of 4-(3-chloro-2-fluoroanilino)-6-[1-(chloroacetyl)piperidin-4-yloxy]-7-methoxyquinazoline (0.14 g) and sodium iodide (0.1 g) in an ethanolic solution of dimethylamine (33%) (10 ml) was stirred at ambient temperature for 2 hours. The mixture was evaporated under vacuum and the residue dissolved in methylene chloride and purified by column chromatography on silica eluting with increasingly polar mixtures of methylene chloride/methanol (saturated with ammonia) (100/0 to 85/15). The fractions containing the title product were combined and evaporated under vacuum and the residue triturated with diethyl ether and filtered to give the title product as a crystalline solid (0.085 g); 1H NMR Spectrum: (DMSO d6) 1.56-1.78 (m, 2H), 1.92-2.08 (m, 2H), 2.20 (s, 6H), 3.05-3.18 (m, 2H), 3.30-3.48 (m, 2H), 3.79-3.90 (m, 2H), 3.94 (s, 3H), 4.75 (m, 1H), 7.21 (s, 1H), 7.28 (t, 1H), 7.44-7.56 (m, 2H), 7.86 (s, 1H), 8.37 (s, 1H), 9.53 (s, 1H); Mass Spectrum: (M+H)+ 488.
