Acetone → 1,1'-{Disulfanediylbis[ethane-2,1-diylimino(4-oxobutane-4,1-diyl)]}bis{4-[{4-[bis(2-hydroxyethyl)amino]phenyl}diazenyl]quinolinium}dichloride

Participants

Reaction Steps

0.35 g of 2,2′-({4-[(quinolin-4-yl)diazenyl]-phenyl}-imino)diethanol and 0.18 g of N,N′-(disulfanediyldiethane-2,1-diyl)bis(4-chlorobutanamide) are solubilized in 2 mL acetonitrile. The mixtured is heated at reflux for 24 h, cooled and poured on 50 mL acetone. The resulting oil is washed several times with acetone.
