実験手順

A mixture of 8-(2-chloroethoxy)-4-(2,4-dichloro-5-methoxyanilino)-7-methoxybenzo[b][1,8]naphthyridine-3-carbonitrile (202 mg, 0.40 mmol) and sodium iodine (70 mg, 0.47 mmol) in 4 mL of morpholine is heated at reflux for 2 hours. The reaction mixture is concentrated in vacuo and partitioned between ethyl acetate and water. The organic layer is washed with saturated sodium bicarbonate, dried over magnesium sulfate, filtered and concentrated in vacuo. Ethyl acetate is added to the residue and the orange solid is collected by filtration to provide 105 mg (47%) of 4-(2,4-dichloro-5-methoxyanilino)-7-methoxy-8-[2-(4-morpholinyl)ethoxy]benzo[b][1,8]naphthyridine-3-carbonitrile, mp 242-244° C. dec.
