After stirring at rt for 18 h, the solvents were evaporated (copious fumes of HBr were produced). The residue was treated with acetic acid (100ml) and re-evaporated, then stirred with water (200ml) and the pH of the suspension was adjusted to pH 4 by addition of solid sodium hydrogen carbonate. The mixture was then stirred at rt for 1 hour then the solid was isolated by filtration with suction to give an off-white damp solid. The product was dried on the sinter with suction for 2 hours then dried in a vacuum desiccator over P2O5 overnight to give the desired compound as a white solid (2.412g, 86%).
