Reaction Steps

tert-Butyl 4-[(4-chloro-6-methoxyquinazolin-7-yl)oxy]piperidine-1-carboxylate was coupled with 3-bromoaniline using an analogous process to that described in Example 21 (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-(3-bromophenyl)-6-methoxy-7-(piperidin-4-yloxy)quinazolin-4-amine hydrochloride; 1H NMR Spectrum: (DMSO d6): 1.8-2.1 (m, 2H), 2.1-2.3 (m, 2H), 3.0-3.35 (m, 4H), 4.05 (s, 3H), 4.88 (m, 1H), 7.38-7.52 (m, 2H), 7.6 (s, 1H), 7.8 (d, 1H), 8.05 (s, 1H), 8.5 (s, 1H), 8.87 (s, 1H), 9.2 (bs, 2H), 11.7 (s, 1H); Mass Spectrum: (M+H)+ 431.
