A mixture of 260 mg (0.56 mmol) of 7-(3-chloropropoxy)-4-(2,4-dichloro-5-methoxyphenylamino)-6-methoxyquinoline-3-carbonitrile (Boschelli, Diane H.; Ye, Fei; Wang, Yanong D.; Dutia, Minu; Johnson, Steve L.; Wu, Biqi; Miller, Karen; Powell, Dennis W.; Yaczko, Deanna; Young, Mairead; Tischler, Mark; Arndt, Kim; Discafani, Carolyn; Etienne, Carlo; Gibbons, Jay; Grod, Janet; Lucas, Judy; Weber, Jennifer M.; Boschelli, Frank. J. Med. Chem. 2001, 44, 3965-3977) and 380 mg (2.24 mmol) of [1,4′]bipiperidinyl are heated in 3 mL of ethylene glycol dimethyl ether at 85° C. for sixteen hours to yield the crude product. Following removal of the solvent in vacuo, the crude product is purified by silica gel chromatography (eluting with 7:3 methylene chloride/methanol) to give 35 mg of 7-(3-[1,4′-bipiperidin]-1′-ylpropoxy)-4-[(2,4-dichloro-5-methoxyphenyl)amino]-6-methoxy-3-quinolinecarbonitrile as a white solid, mp 130-132° C.
