    • 3 (2.25 M equiv) and Pd/C catalyst (5 mol %, Degussa E1002 XU/W, 5 wt%, dry basis, on 50% wet activated carbon) were then added to the reaction flask. The reaction was then placed in a 75°C oil bath and monitored by either HPLC or TLC, where the aryl bromide was completely consumed in less than 1 h. After allowing the reaction to cool to room temperature, the reaction was diluted by adding additional (50 mL) reaction solvent followed by filtering off the Pd/C catalyst
