Participants

Reaction Steps

A solution of 2,4-dinitro-6-bromoaniline (2.5 g, 9.5 mmol), tetramethyltin (6.1 g, 14.3 mmol) and Cl2Pd(PPh3)2 (100 mg) in 10 ml of DMF was stirred at 140° C. for 12 h. Reaction mixture was concentrated in vacuo, yielding an oil which was purified on silica gel column chromatography (CH2Cl2, neat) to provide 1.0 g (3.6 mmol, 41%) of 2,4-dinitro-6-phenylaniline, which was converted to the diamine (0.72 g, >95%) on hydrogenation (H2/Pd-C).
