Versuchsvorschrift

A mixture of 318 mg (0.66 mmol) of 4-(4-chloro-5-methoxy-2-methylanilino)-7-methoxy-8-(chloroethoxy)benzo[g]quinoline-3-carbonitrile and 4-(4-chloro-5-methoxy-2-methylanilino)-8-methoxy-7-(chloroethoxy)benzo[g]quinoline-3-carbonitrile (1:1 mixture), 100 mg of sodium acetate and 5 mL of morpholine is stirred and heated to 130° C. using an oil bath. After 30 minutes the reaction is allowed to cool to room temperature. The reaction mixture is concentrated in vacuo and the residue purified by silica gel chromatography, eluting with 95:5 methylene chloride/methanol to yield 82 mg (23%) of 4-(4-chloro-5-methoxy-2-methylanilino)-7-methoxy-8-[2-(4-morpholinyl)ethoxy]benzo[g]quinoline-3-carbonitrile as a yellow wax and 153 mg of 4-(4-chloro-5-methoxy-2-methylanilino)-8-methoxy-7-[2-(4-morpholinyl)ethoxy]benzo[g]quinoline-3-carbonitrile as a yellow solid, mp 191-194° C. dec.
