A mixture of 0.8 g (1.83 mmol) of 4-(4-chloro-2-fluoro-5-hydroxy-phenylamino)-7-(2-chloro-ethoxy)-6-methoxy-quinoline-3-carbonitrile, 2.4 g (27.5 mmol) of morpholine, and 0.11 g of sodium iodide in 15 ml ethylene glycol dimethyl ether heated in a sealed tube at 135° C. for 12 hr. The solvent was removed and the residue was mixed with warm ethyl acetate and saturated sodium bicarbonate solution. The organic layer was separated and dried over magnesium sulfate. Solvent was removed and the residue was chromatographed on silica gel eluting with ethyl acetate-methanol-triethylamine 70:30:1 giving 0.43 g of the title compound as a tan solid: mass spectrum (electrospray, m/e) M+H 470.0; (M+2H)+2 237.0.
