Product 1

HCID 219564064-[3-chloro-4-(1-methyl-1H-imidazol-2-ylsulfanyl)phenylamino]-7-methoxy-8-[2-(4-methylpiperazin-1-yl)ethoxy]-benzo[g]quinoline-3-carbonitrile

Procedure

Following procedure 1 of Example 149, a mixture of 0.15 g (0.3 mmol) of 8-(2-chloroethoxy)-4-[3-chloro-4-(1-methyl-1H-imidazol-2-ylsulfanyl)phenylamino]-7-methoxybenzo[g]quinoline-3-carbonitrile, 0.5 mL of 1-methylpiperazine and 0.02 g of sodium iodide is heated under reflux for 16 hours. Purification of the material is carried out by silica gel flash chromatography, utilizing a 90:10 to 85:15 gradient of methylene chloride/methanol to give 0.052 g of 4-[3-chloro-4-(1-methyl-1H-imidazol-2-ylsulfanyl)phenylamino]-7-methoxy-8-[2-(4-methylpiperazin-1-yl)ethoxy]-benzo[g]quinoline-3-carbonitrile as a yellow solid, mp 184-186° C.
