Procedure
The title compound (42.0 mg, 77% yield) was prepared as a brown solid from 6-(6,7-dimethoxyquinazolin-4-yloxy)-1-naphthoic acid (37.6 mg, 0.1 mmol) and 4-bromo-o-phenylenediamine (22.4 mg, 0.12 mmol) by an analogous procedure to that described in example 16. 1H NMR (DMSO-d6) δ 4.01 (s, 6H, 2×OCH3), 5.31 (s, 2H, benzene-NH2), 6.77 (d, J=8.3 Hz, 1H, Ar—H), 7.01 (s, 1H, Ar—H), 7.41 (s, 1H, Ar—H), 7.58-7.65 (m, 5H, Ar—H), 7.89 (d, J=7.0 Hz, 1H, Ar—H), 8.00 (s, 1H, Ar—H), 8.14 (d, J=10.2 Hz, 1H, Ar—H), 8.37 (d, J=9.1 Hz, 1H, Ar—H), 8.54 (s, 1H, Ar—H), 9.84 (s, 1H, benzene-NH). LC-MS (m/z) 545 (M+1).
