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-amino-3-chlorobenzofuran 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) 2.0-2.4 (m, 6H), 2.33 (s, 3H), 2.9 (m, 2H), 3.93 (s, 3H), 4.6 (m, 1H), 6.56 (s, 1H), 6.9 (s, 1H), 7.3-7.4 (m, 2H), 7.7 (br s, 1H), 8.64 (s, 1H), 8.7 (d, 1H), 10.3 (br s, 1H); Mass Spectrum: M+H+ 439 and 441.
