Reaction Steps

A mixture of 50 parts of 4-bromo-1-butene, 58 parts of ethyl 4-hydroxybenzoate, 55.2 parts of potassium carbonate and 320 parts of 2-propanone was refluxed for 68 hours. The reaction mixture was evaporated and the residue was dissolved in methylbenzene. The organic solution was washed with a diluted sodium hydroxide solution. The separated organic layer was dried, filtered and evaporated, yielding 25 parts (33%) of ethyl 4-(3-butenyloxy)benzoate as an oily residue (interm. 14).
