Reaction Steps
A mixture of 3,5-dibromo-1-methyl-1H-1,2,4-triazole (142 mg, 0.59 mmol), 1-methylpiperazine (62.0 mg, 0.62 mmol), tris(dibenzylideneacetone)dipalladium(0) (81 mg, 0.09 mmol), BINAP (110 mg, 0.18 mmol) and sodium tert-butoxide (113 mg, 1.18 mmol) in toluene (8 ml) was stirred at 100 °C for 1.5hrs. LCMS indicated no desired product formation. Discarded.
