Buchwald–Hartwig amination: 7-Bromo-4-[(2-fluoro-4-methylphenyl)amino]cinnoline-3-carbonitrile → 4-(2-Fluoro-4-methylphenylamino)-7-(piperazin-1-yl)cinnoline-3-carbonitrile

Drawn from the record's atom map: which bonds break and which form between the reactants and products the source listed. It shows a change in connectivity, not a simulated trajectory and not a mechanism.

Temperature

100 °C

Only the dimensions the source stated are listed. Anything absent here was not recorded, and it is not inferred from what the class usually needs.

A 100 mL flask was charged with 7-bromo-4-(2-fluoro-4-methylphenylamino)cinnoline-3-carbonitrile (0.64 g, 1.79 mmol), Piperazine (0.631 ml, 8.06 mmol), Tris(dibenzylideneacetone)dipalladium (0) (0.131 g, 0.14 mmol), 2-Dicyclohexylphosphino-2',4',6'-tri-iso- propyl-1,1'-biphenyl (0.128 g, 0.27 mmol) and Sodium tert-butoxide (0.548 ml, 4.48 mmol). The mixture was suspended in DMA (25.6 ml) and the reaction mixture was stirred at 100 °C for 30min. The reaction mixture was cooled to rt, diluted with DCM/MeOH (10:1) and filtered over a pad of celite. The filterate was concentrated under reduced pressure, adsorbed onto silica gel and flash chromatography using DCM to DCM/MeOH/NH4OH (10:1:0.1) provided the desired compound as a light orange solid.
