Procedure

A solution of N-[5-(trifluoromethyl)-1,3-benzodithiol-2-ylidene]benzenamine (2.4 g) and methyl iodide (20 ml, excess) in 100 ml of benzene is heated at reflux for 2.5 weeks. The reaction mixture is filtered and recharged with methyl iodide every three days. The combined precipitates (3.3g) are recrystallized from acetonitrile/benzene. The recrystallized product is dried in vacuo at 100° C for 3 days to yield 3.0g of the title compound, melting point 161°-164° C.
