Procedure

The title compound (39.6 mg, 91% yield) was prepared as a brown solid from 6-(7-methoxyquinolin-4-yloxy)-1-naphthoic acid (34.5 mg, 0.1 mmol) and o-phenylenediamine (43.2 mg, 0.4 mmol) by an analogous procedure to that described in example 16. LC-MS (m/z) 1H NMR (DMSO-d6) δ 3.95 (s, 3H, —OCH3), 4.97 (s, 2H, benzene-NH2), 6.60 (d, J=5.2 Hz, 1H, Ar—H), 6.64 (t, J=7.6 Hz, 1H, Ar—H), 6.82 (d, J=7.8 Hz, 1H, Ar—H), 6.99 (t, J=7.4 Hz, 1H, Ar—H), 7.31 (dd, J=2.5 and 9.1 Hz, 1H, Ar—H), 7.38 (d, J=7.6 Hz, 1H, Ar—H), 7.45 (d, J=2.4 Hz, 1H, Ar—H), 7.57 (dd, J=2.4 and 9.2 Hz, 1H, Ar—H), 7.65 (t, J=7.8 Hz, 1H, Ar—H), 7.87-7.88 (m, 2H, Ar—H), 8.07 (d, J=8.2 Hz, 1H, Ar—H), 8.25 (d, J=9.2 Hz, 1H, Ar—H), 8.43 (d, J=9.2 Hz, 1H, Ar—H), 8.65 (d, J=5.2 Hz, 1H, Ar—H), 9.84 (s, 1H, benzene-NH). 436 (M+1).
