Procedure

10.0 g (0.0345 mol) of 8-methyl-2,3-dihydro-1,1,4,4-tetraoxobenz-[1,4]dithiin-7-carboxylic acid were dissolved in 100 ml of toluene, and two drops of dimethylformamide and then 4.5 g (0.038 mol) of thionyl chloride were added. After four hours of stirring under reflux, the mixture was concentrated. The colorless oil that remained (yield 10.6 g) could be directly employed further.
