Versuchsvorschrift

A mixture of 0.1 g (0.3 mmol) of 6,7-diamino-4-(5-methoxy-2-methylanilino)-3-quinolinecarbonitrile and 0.11 g (0.62 mmol) of 2-(4-morpholino)ethylisothiocyanate in 0.3 mL of dioxane is heated at 100° C. for 2 hours under nitrogen. The mixture is cooled and solvent is evaporated to dryness to yield an oil consisting of N-[7-amino-3-cyano-4-(5-methoxy-2-methylanilino)-6-quinolinyl]-N-[2-(4-morpholinyl)-ethyl]thiourea and N-[6-amino-3-cyano-4-(5-methoxy-2-methylanilino)-7-quinolinyl]-N′-[2-(4-morpholinyl)ethyl]thiourea. The oil is dissolved in 3.0 mL of ethanol. To this is added 0.3 g of mercuric oxide and 20 mg of sulphur powder and the resulting mixture is heated at reflux temperature for 2 hours. The product mixture is filtered hot through diatomaceous earth, washed with methanol and solvent is evaporated to yield an oil. The oil is purified by silica gel chromatography, utilizing a gradient of methylene chloride/methanol (95:5 to 85:15) to yield 0.062 g of 8-(5-methoxy-2-methylanilino)-2-{[2-(4-morpholinyl)ethyl]amino}imidazo[4,5-g]quinoline-7-carbonitrile as a pink solid, mp 148–150° C. (shrinks at 140° C.).
