Procedimiento

2.4 g of 1,2-dimethylbenzimidazole, 2.1 g of bis(2-bromoethyl) disulfide and 6 ml of propionitrile were stirred at 100 C in a sealed 20 ml reactor for 8 h. After cooling, filtration, washing with 3 times 10 ml and drying under vacuum, 2.2 g of beige solid were recovered. The analyses showed that the product was in conformity with the expected structure.
