実験手順

A mixture of 0.436 g (0.87 mmol ) of 4-(2,4-dichloro-5-methoxyanilino)-7-methoxy-8-(chloroethoxy)benzo[g]quinoline-3-carbonitrile and 4-(2,4-dichloro-5-methoxyanilino)-8-methoxy-7-(chloroethoxy)benzo[g]quinoline-3-carbonitrile (1:1 mixture), 2.0 mL (23.0 mmol) of morpholine and 0.05 g of sodium iodide in 2.0 mL of ethylene glycol dimethyl ether is heated at 90° C. for 3.5 hours under nitrogen. The mixture is cooled, solvent is removed in vacuo and the resulting residue is stirred with a saturated solution of sodium bicarbonate. The crude solid is collected by filtration, washed with water, and dried in vacuo. Purification is carried out by silica gel chromatography, eluting with a gradient of 97:3 to 90:10 ethyl acetate/methanol to yield 0.241 g of 4-(2,4-dichloro-5-methoxyanilino)-8-methoxy-7-[2-(4-morpholinyl)ethoxy]benzo[g]quinoline-3-carbonitrile as a yellow solid, mp 210-212° C. and 0.203 g of 4-(2,4-dichloro-5-methoxyanilino)-7-methoxy-8-[2-(4-morpholinyl)ethoxy]benzo[g]quinoline-3-carbonitrile as a yellow solid, mp 207-214° C.
