Reaction Steps

2-Bromo-4-methyl-1-(4-methylphenyl)pentan-1-one (13.5 g, 50 mmol) and potassium phthalimide (9.26 g, 50 mmol) were thoroughly mixed and heated at 160° C. for 2 hours. After cooling, to the reaction mixture were added ethyl acetate (100 ml) and water (50 ml). The resulting organic layer was separated and washed with brine. The organic solution was then dried over sodium sulfate and evaporated under reduced pressure. The residue was crystallized by treatment with hexane and the crystals were recrystallized from hexane to obtain 12.2 g of the title compound as white crystals (yield: 73%).
