Reaction Steps

In a heavy-walled PYREX tube was placed 2-iodoaniline (2.84 g, 13 mmol), dimethylmaleate (2.44 g, 17 mmol), triethylamine (1.4 mL, 10 mmol), palladium diacetate (31 mg, 0.14 mmol) and 6 mL acetonitrile. The tube was flushed with nitrogen and sealed. The sealed tube was heated at 100° for 3.5 h then cooled to r.t. The tube was opened and the resulting solids filtered and washed with acetonitrile. The solids were dissolved in chloroform and the solvent removed under vacuum to provide a solid.
