1,3-Cyclohexanedione → HCID 69916320, compound

Participants

Reaction Steps

1.150 g (3.20 mmol) of 2,4-dibromo-3-(cyclobutylmethoxy)benzoic acid, 0.39 g (3.50 mmol) of cyclohexane-1,3-dione, 0.618 g (3.20 mmol) of N′-(3-dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride and 0.004 g of dimethylaminopyridine were stirred for 10 hours at room temperature in 30 ml of methylene chloride. The mixture was subsequently diluted with methylene chloride and washed with 0.5 N HCl, with water, with saturated NaHCO3 solution and again with water. After the combined organic phases had been dried over Na2SO4 and evaporated completely on a rotary evaporator, 3-oxo-1-cyclohexenyl 2,4 dibromo-3-cyclobutylmethoxybenzoate was obtained in the form of a yellow resin.
