A solution of 5-chloro-N-phenyl-1,3-benzodithiol-2-imine (6.0g) and methyl iodide (50 ml, excess) in 200 ml of dry benzene is heated at 50° C for 72 hours. The reaction mixture is filtered and the resultant solid is washed several times with pentane. The solid product is recrystallized from n-amyl alcohol to yield 4.0g of the title compound, melting point 205°-207° C.
