Reaction Steps
5-Bromo salicylaldehyde (10.05 g), bromo acetone (8.0 g) and potassium carbonate (13.80 g) were refluxed for 1 hr in 2-butanone (100 ml). 2-Butanone (ca. 50 ml) was evaporated and ice was added. The precipitate was collected by filtration and washed with water and hexane to give the objective compound (10.50 g).
