5-Methoxy-2-methylbenzo[d]thiazole-4,7-dione → 5.5'-[(Methylimino)bis(butane-4,1-diylimino)]bis(2-methyl-1,3-benzothiazole-4,7-dione)

Reaction Conditions

Reaction Steps

6 mg (34 μmol) of N-(4-aminobutyl)-N-methylbutane-1,4-diamine is added to a solution of 15 mg (71 mmol; 2.1 equivalents) of 5-methoxy-2-methyl-1,3-benzothiazole-4,7-dione in 1.5 ml of ethanol, then the reaction mixture is stirred at 60° C. for 1 hour. The solvent is then evaporated off under reduced pressure and the expected product is obtained by purification by chromatography on a silica column (eluent: dichloromethane/methanol: 95/5) in the form of a red oil.
