Procedure
Using an analogous procedure to that described in Example 5, 4-chloro-7-methoxy-5-(N-methylpiperidin-4-yloxy)quinazoline was reacted with 7-aminobenzofuran to give the title compound, a portion of which was treated with a saturated methanolic ammonia solution. The mixture was filtered and the filtrate was evaporated to give the free base; NMR Spectrum: (CDCl3) 2.15–2.35 (m, 6H), 2.32 (s, 3H), 2.92 (m, 2H), 3.9 (s, 3H), 4.6 (m, 1H), 6.5 (d, 1H), 6.8 (d, 1H), 6.85 (d, 1H), 7.25–7.4 (m, 2H), 7.68 (d, 1H), 8.58 (d, 1H), 8.6 (s, 1H), 10.25 (br s, 1H); Mass Spectrum: M+H+ 405.
