Reaction Steps

Pyrrolidine (10 ml) was added to a mixture of 7-[2-(2-chloroethoxy)ethoxy]-3-cyano-6-methoxy-4-[4-(3-methoxyprop-1-ynyl)-2,3-methylenedioxyanilino]quinoline (0.225 g) and sodium iodide (0.133 g) and the reaction mixture was stirred at ambient temperature for 24 hours. The reaction mixture was evaporated and the residue was triturated under methylene chloride. The resultant solid was washed with water and dried. The material so obtained was dissolved in the minimum quantity of ethyl acetate and a solution of hydrogen chloride in diethyl ether (1M) was added. The resultant solid was isolated, washed with diethyl ether and dried. There was thus obtained the title compound as a solid (0.145 g); NMR Spectrum: (DMSOd6 and CD3CO2D at 100° C.) 1.84–1.89 (m, 4H), 3.29–3.39 (m, 9H), 3.88 (m, 2H), 3.94 (m, 2H), 3.96 (s, 3H), 4.3 (s, 2H), 4.36 (m, 2H), 6.04 (s, 2H), 6.84 (d, 1H), 6.94 (d, 1H), 7.46 (s, 1H), 7.87 (s, 1H), 8.56 (s, 1H); Mass Spectrum: M+H+ 545.
