A slurry of 2.98 g of 3-[(1,3-benzodithiol-2-ylidene)amino]-2-thioxo-4-thiazolidinone (see example 37), phenylacetaldehyde (10 ml, excess) and acetic acid/piperidine (10 drops) in 600 ml of anhydrous glyme is heated at reflux for four days. The reaction mixture is filtered while hot, and the solid is collected and recrystallized from dimethylformamide to yield 1.78 g of the title compound, melting point 233°-234° C.
