Reaction Steps

A solution of N'-(1,3-benzodithiol-2-ylidene)-N,N-dimethyl-1,2-ethanediamine (2.0g, prepared as described in Example 15) in 100 ml of diethyl ether is treated dropwise with ethereal hydrogen chloride until precipitation is complete. The white solid thus obtained is filtered, washed with diethyl ether, and recrystallized from acetonitrile. The recrystallized material was filtered and washed with diethyl ether before drying over phosphorous pentoxide for four days. Analysis of this product (1.4g) indicates it to be a mixture of mono- and dihydrochloride. The product is recrystallized from ethanol with the addition of 5 ml of ethereal hydrogen chloride. The recrystallized solid is filtered under nitrogen, washed with diethyl ether, and dried under nitrogen at atmospheric pressure to yield 1.2g of the title compound, melting point 218°-220° C.
