Procedure
Using an analogous procedure to that described in Example 5, 4-chloro-7-methoxy-5-(N-methylpiperidin-4-yloxy)quinazoline was reacted with 2,3-methylenedioxyaniline (J. Med. Chem., 1979, 2, 1354) 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) 2.0-2.1 (m, 2H), 2.15-2.3 (m, 4H), 2.31 (s, 3H), 2.85 (m, 2H), 3.91 (s, 3H), 6.01 (s, 2H), 6.5 (d, 1H), 6.68 (d, 1H), 6.82 (d, 1H), 6.91 (m, 1-1), 8.0 (d, 1H), 8.6 (s, 1H), 9.72 (s, 1H); Mass Spectrum: M+H+ 409.
