P-Phenylenediamine → 4-(4'-Aminoanilino)-6,7-dimethoxyquinazoline hydrochloride

Participants

Reaction Steps

Using an analgous procedure to that described in Example 74, 4-chloro-6,7-dimethoxyquinazoline was reacted with 1,4-phenylenediamine to give 4-(4'-aminoanilino)-6,7-dimethoxyquinazoline hydrochloride in 85% yield, m.p. 274°-276° C. NMR Spectrum: (CD3SOCD3) 3.95 (s, 3H), 3.98 (s, 3H), 6.75 (d, 2H), 7.35 (s, 1H), 7.38 (d, 2H), 8.25 (s, 1H), 8.67 (s, 1H), 11.05 (broad s, 1H); Elemental Analysis: Found C, 57.6; H, 5.0; N, 16.9; C16H16N4O2. 1HCl requires C, 57.7; H, 5.15; N, 16.8%.
