YieldReaction ConditionsOperation in experiment
21% With formamide; at 130℃; for 5h;Inert atmosphere; 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 (21percent of theory) of the target compound.LC-MS (method 15): Rt=0.56 min; m/z=184 (M+H)+.1H-NMR (400 MHz, DMSO-d6): delta=11.58 (br. s, 1H), 7.71 (t, 2H).
