Procedure

A solution of 8-amino-quinoline (12.91 g, 89 mmol) and bis(2-chloroethyl)-benzylamine (25.95 g, 112 mmol) in n-butanol (65 ml) was allowed to heat at 85° C. for 11 hours. The mixture was poured into 50% sodium hydroxide, extracted with methylene chloride and water. The organic layer was dried over anhydrous magnesium sulfate, and filtered. The solvent was removed under vacuum. Chromatography (methanol-methylene chloride) afforded 12.34 g of product as a solid: mp 116.5-118° C.
