Procedure

Methyl 3-benzyloxy-4-(4-ethylbenzyl)benzoate (1.6 g) was dissolved in a mixed solvent of tetrahydrofuran (5 mL) and ethanol (5 mL). To the solution was added 2 mol/L aqueous sodium hydroxide solution (10 mL), and the mixture was stirred at 80° C. for 1 hour. The reaction mixture was cooled to ambient temperature, acidified with 2 mol/L hydrochloric acid, and the mixture was stirred under ice-cooling for 30 minutes. The resulting precipitated crystals were collected by filtration, washed with water and dried to give 3-benzyloxy-4-(4-ethylbenzyl)benzoic acid (1.4 g).
