Reaction Conditions

Reaction Steps

In a 50 mL round-bottomed flask, PALLADIUM ACETATE (0.014 g, 0.06 mmol) was treated with BINAP (0.079 g, 0.13 mmol) under nitrogen in degassed Toluene (12.74 ml). The reaction was heated to 80 °C and was stirred for 10 min. To the flask was then added tert-butyl piperazine-1-carboxylate (0.237 g, 1.27 mmol), cesium carbonate (0.208 g, 0.64 mmol), potassium carbonate (0.176 g, 1.27 mmol), and 18-CROWN-6 (0.034 g, 0.13 mmol). The reaction was then treated with 4-bromo-2-chloro-1-ethoxybenzene (0.300 g, 1.27 mmol) and was allowed to stir at 80°C 5 h. **LCMS High pH:** No reaction observed
