Reaction Steps

2-Chloro-5-nitropyridine (510 mg, 3.22 mmol), (3,4,5,6-tetrahydro-1H-pyrrolo[3,4-c]pyrrol-2-yl)(2-trifluoromethylphenyl)methanone trifluoroacetate (1.046 g, 2.64 mmol) and cesium carbonate (1.72 g, 5.28 mmol) were stirred in 20 ml of DMF at 80° C. for 5 h. After concentrating under reduced pressure, ethyl acetate and water were added, and the precipitated solid was filtered off with suction. The organic phase was removed and concentrated. The two precipitates were combined. Yield: 845 mg (79%), M+H+: 405.04.
