Procedure

With stirring, 3 g (10.63 mmol) of 2,6-dimethyl-1H,5H-[1,4]dithiino[2,3-c:5,6-c′]dipyrrole-1,3,5,7(2H,6H)-tetrone [compound No. (1)] were added to 20 ml of ice-cooled (5° C.) fuming nitric acid. After dissolution was complete, stirring was continued for 5 min, the mixture was subsequently poured into ice-water and the yellow crystals were filtered off with suction. This gave 2.56 g (80.8% of theory) of the desired compound.
