Diphenylamine → HCID 266861, compound

Participants

Reaction Steps

A 1 L round bottom flask was charged with diphenylamine (13.29 g, 79.0 mmol), 1-iodo-3-nitrobenzene (19.56 g, 79.0 mmol), palladium (II) acetate (0.70 g, 3.12 mmol), biphenyl-2-dicyclohexylphosphine (2.19 g, 6.25 mmol), sodium tert-butoxide (10.48 g, 109 mmol) and toluene (400 mL). This was stirred at reflux for 18 h. The mixture was then filtered. The filtrate was concentrated in vacuo, and the crude product was chromatographed (silica gel) using a gradient of 10-20% dichloromethane in hexane to give 3-nitro-N,N-diphenylaniline (14.15 g, 62%) as an orange solid.
