Versuchsvorschrift

A stirred mixture of 17.2 g (0.033 mole) of 8-amino-5-dimethylamino-6-methoxyquinoline and 9.8 g (0.033 mole) of 4-bromo-1-phthalimidopentane was maintained at 145° while 5 ml of triethylamine was added dropwise. Addition of 9.8 g of 4-bromo-1-phthalimidopentane and 5 ml of triethylamine was repeated three more times, at the same temperature (145°) at 2 hr intervals. The mixture was allowed to cool, diluted with acetone and filtered. The filtrate was concentrated to a brown oil which was diluted with ether, washed with 30% KOH and extracted with chloroform. The extract was passed through a silica column and the eluate was concentrated, dissolved in ether, treated with Darco and slowly evaporated to give yellow crystals which, after washing with petroleum ether (bp 20°-40°) weighed 9.5 g and melted at 103°-105°.
