Participants

Reaction Steps

Under argon, 2.15 g (11.68 mmol) of 4,7-difluoro-2-benzofuran-1,3-dione were stirred in 15 ml of formamide at 130° C. for 5 h. The cooled reaction mixture was then added to ice-water. A solid precipitated out. This solid was filtered off with suction and washed with water. The product was dried under high vacuum. This gave 0.45 g (21% of theory) of the target compound.
