Reaction Steps

A mixture of 1,4 dibromobutane (50 ml), methyl 4-hydroxy-benzoate (15.2 g, 0.1 mole), potassium carbonate (40 g) in 2-butanone (500 ml) was refluxed for 24 hours. The mixture was filtered, solvent removed and the residue was chromatographed on silica gel eluted with chloroform/petrol and recrystallised from pentane to give methyl 4-(4-bromobutyloxy)benzoate (19.26 g).
