Procedure
A mixture of 4-(6-chloro-2,3-methylenedioxyanilino)-7-(3-piperazin-1-ylpropoxy)-5-tetrahydropyran-4-yloxyquinazoline (1.3 g), 2-chloroacetonitrile (0.167 ml), sodium iodide (0.036 g), potassium carbonate (0.331 g) and DMF (15 ml) was stirred at ambient temperature for 5 hours. The mixture was evaporated and the residue was partitioned between ethyl acetate and water. The organic phase was washed with brine, dried over magnesium sulphate and evaporated. The residue was purified by column chromatography on silica using a 10:9:1 mixture of ethyl acetate, methylene chloride and methanol as eluent. There was thus obtained the title compound (0.69 g); NMR Spectrum: (CDCl3) 1.85-2.0 (m, 4H), 2.1 (m, 2H), 2.4-2.5 (m, 6H), 2.5-2.6 (m, 4H), 3.42 (s, 2H), 3.5-3.6 (m, 2H), 3.9-4.0 (m, 2H), 4.0-4.1 (m, 2H), 4.7 (m, 1H), 6.0 (s, 2H), 6.42 (s, 1H), 6.65 (d, 1H), 6.78 (d, 1H), 6.9 (d, 1H), 8.42 (s, 1H), 9.2 (s, 1H); Mass Spectrum: M+H+ 581 and 583.
