Reaction Steps

5-bromo-2-iodo-4-methoxypyrimidine (0.086 g, 0.27 mmol), diacetoxypalladium (2.78 mg, 0.01 mmol), di((3S,5S,7S)-adamantan-1-yl)(butyl)phosphine (8.88 mg, 0.02 mmol) and sodium 2-methylbutan-2-olate (0.033 g, 0.30 mmol) were added to a micro vial. Then N-ethylaniline (0.031 mL, 0.25 mmol) in toluene (1.5 mL) was added to the reaction mixture. The vial was sealed and evacuated and flushed with nitrogen and then stirred at 60°C o/n. LC/MS showed product formation. The reaction mixture was cooled to rt and then filtered over celite. The crude product was diluted with 25 ml of DCM and then washed with sat. NaHCO3 followed by brine. The organic phase was dried over a phase separator and then concentrated to dryness. **No LC/MS data due to database failure over three months and was only saved locally on LC/MS computer and pdf-files seems to be deleted on machine. Not used in further reactions.**
