Reaction Steps

4.0M HCl in Dioxane (4.0 ml) was added to a stirred suspension of 7-(benzyloxy)-4-chloro-6-methoxyquinazoline (60 g, 0.2 mol) [prepared as described in WO98/13354, Example 1] and 3-chloro-2-fluoroaniline (31.96 g, 0.22 mol) in acetonitrile (1200 mL). The reaction mixture was heated at 80° C. for 1 hour then left to stand O/N. Acetonitrile (500 mL) was added and the resulting precipitate filtered, washed with Acetonitrile (3×500 mL) and dried under vacuum to give 7-(benzyloxy)-N-(3-chloro-2-fluorophenyl)-6-methoxyquinazolin-4-amine hydrochloride 2 as a beige solid (85.45 g, 96%); 1H NMR Spectrum: (DMSO d6) 4.02 (s, 3H), 5.35 (s, 2H), 7.30-7.60 (m, 9H), 7.65 (m, 1H), 8.38 (s, 1H), 8.85 (s, 1H), 11.8 (s, 1H); Mass Spectrum: (M+H)+ 410.27.
