Reaction Steps
tert-Butyl 4-[(4-chloro-6-methoxyquinazolin-7-yl)oxy]piperidine-1-carboxylate was coupled with tert-butyl (3-bromo-2-fluorophenyl)carbamate 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-(3-bromo-2-fluorophenyl)-6-methoxy-7-(piperidin-4-yloxy)quinazolin-4-amine hydrochloride; 1H NMR Spectrum: (DMSO d6) 1.85-2.1 (m, 2H), 2.1-2.32 (m, 2H), 3.0-3.35 (m, 4H), 4.02 (s, 3H), 4.83-5.0 (m, 1H), 7.3 (dd, 1H), 7.5-7.65 (m, 2H), 7.75 (dd, 1H), 8.45 (s, 1H), 8.8(s, 1H), 9.15 (bs, 2H), 11.86 (s, 1H); Mass Spectrum: (M+H)+ 447.12.
