Reaction Steps

N-Bromosuccinimide (2.0 g, 11.2 mmol) was added to a solution of 7-hydroxy-2-methyl-3-phenyl-chromen-4-one (2.5 g, 10 mmol) in DMF (20 ml) and the solution stirred for ˜24 hrs. to give an orange suspension. The suspension was poured into water (200 ml) to give a pale pink precipitate, solids were removed by filtation and washed with water. Solids were recrystallised from ethanol, to give the 8-bromo-7-hydroxy-2-methyl-3-phenyl-chromen-4-one as an off-white solid (1.95 g)
