Procedure

4-(3-chloro-2-fluoroanilino)-7-methoxy-6-{[(2S)-1-(chloroacetyl)pyrrolidin-2-yl]methoxy}quinazoline (0.45 g, 0.94 mmole) was dissolved in morpholine (7.5 ml) and stirred at ambient temperature overnight in the presence of potassium iodide (10 mg). The solvent was evaporated and the residue purified by column chromatography eluting with methylene chloride/methanol (saturated with ammonia) (98/2). The fractions containing the expected product were combined and evaporated under vacuum to give the title product as a foam (0.22 g, 44%); 1H NMR Spectrum: (CDCl3) 1.91-2.01 (m, 1H); 2.06-2.14 (m, 2H); 2.19-2.27 (m, 1H); 2.48-2.53 (m, 2H); 2.62-2.68 (m, 2H); 3.18 (q, 2H); 3.41-3.52 (m, 1H); 3.56-3.72 (m, 5H); 4.01-4.08 (m, 4H); 4.53 (d, 1H); 4.72 (t, 1H); 7.11-7.28 (m, 3H); 7.96 (m, 1H); 8.36 (s, 1H); 8.60 (s, 1H); 8.63 (s, 1H); Mass Spectrum: (M−H)− 528.
