Vorschrift

A mixture of compound 1,2-dimethyl-1H-benzimidazole (2.93 g, 20 mmol) and N,N′-(disulfanediyldiethane-2,1-diyl)bis(2-chloroacetamide) (1.53 g, 5 mmol) in 20 ml of acetonitrile was heated to reflux for 24 h. After cooling, the resulting white solids were collected by filtration and washed with ethyl acetate and dichloromethane to afford 1.94 g of a white powder. Analyses were in accordance with the expected structure.
