Sodium Iodide → 4-[3-chloro-4-(1-methyl-1H-imidazol-2-ylsulfanyl)phenylamino]-7-methoxy-8-(2-morpholin-4-yl-ethoxy)benzo[g]quinoline-3-carbonitrile

Participants

Reaction Steps

A mixture of 1.27 g (2.3 mmol) of 8-(2-chloroethoxy)-4-[3-chloro-4-(1-methyl-1H-imidazol-2-ylsulfanyl)phenylamino]-7-methoxybenzo[g]quinoline-3-carbonitrile, 4.0 mL of morpholine and 0.1 g of sodium iodide in 10 mL of 1,2-dimethoxyethane is heated under reflux for 16 hours. After allowing the reaction to cool, the solvent is evaporated to yield a residue, which is stirred with saturated sodium bicarbonate. The solid is collected by filtration, is washed with water and dried. The crude product is purified by silica gel chromatography, utilizing a gradient of 98:2 to 90:10 of methylene chloride/methanol to give 0.53 g of 4-[3-chloro-4-(1-methyl-1H-imidazol-2-ylsulfanyl)phenylamino]-7-methoxy-8-(2-morpholin-4-yl-ethoxy)benzo[g]quinoline-3-carbonitrile as a yellow solid, mp>300° C.
