Versuchsvorschrift

2,3-difluoro-1,4-di(2-thienyl)-5,6-diamino-benzene (1.2 g, 3.9 mmol) was added into a small flask and purged with Ar three times. Then, dry pyridine (24 ml), N-thionylaniline (1.08 g, 7.8 mmol) and chlorotrimethylsilane (0.76 g, 7.0 mmol) were added. The mixture was stirred at 80° C. for 16 h before poured into ice water. The yellow precipitate was then filtered and washed with a mixture of ethanol and water (1:1 v/v) to afford 5,6-difluoro-4,7-di(2-thienyl)-2,1,3-benzothiadiazole as a yellow solid (1.3 g, 98%). 1H and 19F NMR spectra were as expected.
