Reaction Steps

A mixture of 2,5-dibromopyridine (15.0 g, 63.9 mmol), N-acetyl-propargylamine (15.51 g), and PdCl2(PPh3)2 (453 mg) in diisopropylamine (510 mL) was refluxed for 3 hours under a nitrogen atmosphere. To the mixture was added water (200 ml) and diisopropylamine was removed from the mixture by distillation under reduced pressure. The resulting suspension was aged at ambient temperature for 1 hour, and precipitates were collected by filtration and dried under reduced pressure to provide 2-1 (14.0 g).
