A mixture of 222.5 mg (0.5 mmol) of 7-(2-chloroethoxy)-6-methoxy-4-(4-phenoxyphenylamino)quinolin-3-carbonitrile, 841.4 mg (5.0 mmol) of 4-piperidinopiperidine and 49.5 mg (0.33 mmol) of sodium iodide in 6.0 mL of ethylene glycol dimethyl ether are heated in a sealed tube at 135-140° C. for 17 hours to yield the crude product. Solvents are removed in vacuo. Purification of the oily residue is carried out by preparative thin layer chromatography (eluting with 85:15 dichloromethane/methanol) to provide 137.7 mg of 742-[1,4′]bipiperidinyl-1′-yl-ethoxy)-6-methoxy-4-(4-phenoxy-phenylamino)-quinoline-3-carbonitrile as a light yellow solid, mp 141° C. (decompose).
