A mixture of 4-chloro-5-morpholino-7-(2-pyrrolidin-1-ylethoxy)quinazoline (0.27 g), 6-chloro-2,3-methylenedioxyaniline (0.14 g) and isopropanol (4 ml) was stirred and heated to 80° C. for 1 hour. The mixture was evaporated and the residue was dissolved in a 49:1 mixture of methylene chloride and a saturated methanolic ammonia solution. The mixture was filtered and the filtrate was poured onto a column of silica and eluted with a 97:3 mixture of methylene chloride and a saturated methanolic ammonia solution. The material so obtained was triturated under diethyl ether. The resultant solid was isolated, washed with diethyl ether and dried under vacuum. There was thus obtained the title compound (0.035 g); NMR Spectrum: (CDCl3) 1.85 (br s, 4H), 2.65 (br s, 4H), 3.0 (m, 2H), 3.08 (m, 2H), 3.18 (d, 2H), 3.82 (m, 2H), 4.05 (m, 2H), 4.25 (m, 2H), 6.05 (s, 2H), 6.75 (d, 1H), 6.95–7.1 (m, 3H), 8.52 (s, 1H); Mass Spectrum: M+H+ 498 and 500.
