Reaction Steps

In a 100 ml RBF, 3-bromopyridine (1.220 mL, 12.66 mmol) was taken in xylenes (20 mL). To this was added tris(dibenzylideneacetone)dipalladium(0) (0.232 g, 0.25 mmol), tri-t-butylphosphine (10%wt in Hexane) (1.281 g, 0.63 mmol) and sodium tert-butoxide (1.825 g, 18.99 mmol). Then piperazine (6.54 g, 75.95 mmol) was added to RM and the RM was then heated at 130 °C for 5 hrs. The reaction was monitored by LCMS. It did not show formation of product. The RM was discarded.
