The resulting organic phases were dried over Na2SO4 and concentrated. To this flask was added 6-bromo-8-amino-quinoline (2.15 g, 9.6 mmol), n-BuOH (100 mL), and Et3N (4 mL, 28.9 mmol). The resulting reaction mixture was stirred at 100° C. overnight. TLC analysis showed starting amine was still present, therefore an additional portion of bis(2-chloroethyl)-benzylamine hydrochloride (5 g) was added. The reaction was heated an additional 72 hours. The cooled reaction mixture was quenched with 1 M NaOH (200 mL) and extracted into EtOAc (3×200 mL). The organic fractions were combined, dried over Na2SO4, and concentrated. The resulting gold oil was purified three times by column chromatography (40% EtOAc/hexanes) affording 1.2 g (33%) of a viscous orange oil which solidified upon standing: mp 65-68° C., MS (+) APCI m/z 382 [M+H]+.
