Reaction Steps

A mixture of 4-chloro-6-methoxy-7-(3-morpholinopropoxy)quinazoline (0.1 g), 2,3-methylenedioxyaniline (0.048 g), pentan-2-ol (5 ml) and a solution of hydrogen chloride in isopropanol (6M, 4 drops) was stirred and heated to 100° C. for 5 hours. The resultant mixture was cooled to ambient temperature and the precipitate was isolated by filtration, washed with pentan-2-ol and dried under vacuum. There was thus obtained the title compound (0.138 g) as a dihydrochloride salt; NMR Spectrum: (DMSOd6 and CF3COOD) 2.35 (m, 2H), 2.5 (m, 2H), 3.15 (m, 2H), 3.3 (m, 2H), 3.55 (d, 2H), 3.8 (t, 2H), 4.05 (s, 3H), 4.35 (t, 2H), 6.1 (s, 2H), 7.0 (m, 3H), 7.4 (s, 1H), 8.2 (s, 1H), 8.85 (s, 1H); Mass Spectrum: M+H+ 439; Elemental Analysis: Found C, 52.8; H, 5.56; N, 10.68; C23H26N4O52HCl0.5H2O requires C, 53.08; H, 5.62; N, 10.77%.
