Procedure
tert-butyl 4-[(4-chloro-6-methoxyquinazolin-7-yl)oxy]piperidine-1-carboxylate was coupled with 2-fluoro-5-chloroaniline using an analogous process to that described in Example 22 (preparation of starting materials) for the preparation of N-(3-chloro-4-fluorophenyl)-6-methoxy-7-(piperidin-4-yloxy)quinazolin-4-amine hydrochloride, to give N-(5-chloro-2-fluorophenyl)-6-methoxy-7-(piperidin-4-yloxy)quinazolin-4-amine hydrochloride; 1H NMR Spectrum: (DMSO d6) 1.8-2.1 (m, 2H), 2.1-2.35 (m, 2H), 3.0-3.35 (m, 4H), 4.05 (s, 3H), 4.8-5.0 (m, 1H), 7.4-7.55 (m, 2H), 7.55-7.75 (m, 2H), 8.45 (s, 1H), 8.82 (s, 1H), 9.22 (bs, 2H), 11.94 (s, 1H); Mass Spectrum: (M+H)+ 403.
