Procedure

N,N-Dimethylaminoacetyl chloride hydrochloride (100 mg) was added portionwise to a stirred solution of N-(3-chloro-2-fluorophenyl)-6-methoxy-7-(piperidin-4-yloxy)quinazolin-4-amine dihydrochloride (250 mg, 0.57 mmol) and diisopropylethylamine (300 μl) in methylene chloride (25 ml) at 0° C. The reaction mixture was allowed to stir for 2 hours to room temperature. The reaction mixture was washed with saturated sodium bicarbonate solution (25 ml), dried (MgSO4), filtered and evaporated. The residues were purified by column chromatography eluting with increasingly polar mixtures of methylene chloride/methanol (100/0 to 90/10), followed by methylene chloride/methanol (saturated with ammonia) (90/10). The fractions containing the desired product were combined and evaporated under vacuum to give the title product as a white foam (0.125 g, 45%); 1H NMR Spectrum: (DMSO d6) 1.50-1.65 (m, 1H); 1.65-1.80 (m, 1H); 1.95-2.15 (m, 2H); 2.25 (s, 6H); 3.10-3.50 (m, 4H); 3.75-4.05 (m, 2H); 3.95 (s, 3H); 4.90 (m, 1H); 7.30 (m, 1H); 7.35 (s, 1H); 7.40-7.60 (m, 2H); 7.85 (s, 1H); 8.40 (s, 1H); 9.65 (s, 1H); Mass Spectrum: (M+H)+ 488.
