Using an analogous procedure to that also described in the portion of Example 31 that is concerned with the preparation of starting materials, 5-(1-tert-butoxycarbonylpiperidin-4-yloxy)-4-chloro-7-methoxyquinazoline (0.14 g) and 6-chloro-2,3-methylenedioxyaniline (0.064 g) were reacted to give 5-(1-tert-butoxycarbonylpiperidin-4-yloxy)-4-(6-chloro-2,3-methylenedioxyanilino)-7-methoxyquinazoline dihydrochloride (0.17 g); NMR Spectrum: (DMSOd6) 1.42 (s, 9H), 1.8-2.0 (m, 2H), 2.0-2.15 (m, 2H), 3.0-3.2 (m, 2H), 3.85-3.95 (m, 2H), 3.99 (s, 3H), 5.1 (m, 1H), 6.96 (d, 1H), 7.05 (d, 1H), 7.12 (s, 1H), 7.15 (d, 1H), 8.78 (s, 1H), 10.1 (s, 1H); Mass Spectrum: M+H+ 529 and 531.
