Procedure

Reaction of 30 g (0.22 mole) of 4,5-dimethyl-1,2-phenylenediamine with potassium ethylxanthate using the method described in Example 86 yielded 19 g of 5,6-dimethyl-2-mercaptobenzimidazole, as confirmed by the nmr and infrared spectra and by elemental analysis. The title compound (3.0 g) was prepared by the method of Example 84 using 3.5 g of 5,6-dimethyl-2-mercaptobenzimidazole instead of 2-mercaptobenzimidazole. Structure assignment was supported by the nmr spectrum.
