Yield:1208-86-2 100%

Reaction Conditions:

with C31H26N4PPdS(1+)*Cl(1-);sodium t-butanolate in toluene at 95; for 9 h;Catalytic behavior;

Steps:

2.5.4. General procedure for C-N coupling reactions

General procedure: In a typical run, an oven-dried 10 mL round bottom flask wascharged with a known mole percent of catalyst, NaOt-Bu(1.3 mmol), aryl amine (1.2 mmol) and aryl halide (1 mmol) withthe appropriate solvent(s) (4 mL). The flask was placed in a preheatedoil bath at required temp. After the specified time the flaskwas removed from the oil bath, water (20 mL) was added, and extraction with ether (4 10 mL) was done. The combined organiclayers were washed with water (3 10 mL), dried over anhydrousNa2SO4, and filtered. Solvent was removed under vacuum. The residuewas dissolved in hexane and analyzed by GC-MS using Elite-5columns, which are fused silica capillary columns coated with 5%diphenyl and 95% dimethyl polysiloxane.
