反応手順

To a solution of 33.0 g (196 mmol) of methyl 2,4-dihydroxybenzoate and 68.0 g (491 mmol) of potassium carbonate mixed in 500 ml of 2-butanone was added 50 ml (235 mmol) of octyl bromide and the whole was refluxed for 18 hours. Water was added to the solution and the whole was extracted with ethyl acetate. After removal of the solvent by distillation, the residue was purified by silica gel column chromatography to obtain 40.4 g of methyl 2-hydroxy-4-octyloxybenzoate (29) as a colorless clear liquid (yield: 73.5%).
