Triethylamine → 6-Methoxy-4-methyl-8-(1-methyl-4-phthalimidobutylamino)-5-(6-phenylhexoxy) quinoline

Participants

Reaction Steps

A stirred mixture of 8-amino-6-methoxy-4-methyl-5-(6-phenylhexoxy) quinoline hydrochloride (2.7 g, 0.007 mol), and 4-iodo-1-phthalimido-pentane (IPP) (3.0 g, 0.009 mol) was maintained at 100° C. while 1 ml of Et3N was added dropwise. After an additional 3 h of IPP and 1 ml of Et3N were added, heating was continued for 4 h and the mixture was allowed to cool, diluted with Et2O (100 ml), filtered, washed with saturated NaCl and dried (Na2SO4). Solvent removal provided a quantitative yield of 6-methoxy-4-methyl-8-(1-methyl-4-phthalimidobutylamino)-5-(6-phenylhexoxy) quinoline as a brown syrup which was used without further purification.
