Procedure

Following the procedure of Example 11, a mixture of 220 mg (0.5 mmol) of 4-[3-chloro-4-(1-methyl-1H-imidazole-2-ylsulfanyl)phenylamino]-7-fluoro-6-methoxyquinoline-3-carbonitrile and 290 mg (1.72 mmol) of 4-piperidinopiperidine in 1.5 mL of 1-methyl 2-pyrrolidinone is heated at 105° C. for 17 hours to yield the crude product. Purification by silica gel chromatography (gradient 94:6 methylene chloride/methanol to 89:10:1 methylene chloride/methanol/ammonium hydroxide) gives 193 mg of 7-(1,4′-bipiperidin-1′-yl)-4-{3-chloro-4-[(1-methyl-1H-imidazole-2-yl)thio]phenyl}amino)-6-methoxyquinoline-3-carbonitrile as a beige solid, mp 221-223° C.
