실험 절차

0.36 g of 2-(4-hydroxy-2,6-dimethylphenyl)acetic acid was treated with 184 mg of a 60% dispersion of sodium hydride in mineral oil and 0.72 g of benzyl bromide in 10 ml of dry dimethylformamide. The solvent was removed by evaporation and the residue was partitioned between water and methylene chloride. The organic layer was evaporated to give 0.63 g of crude product of melting point 54°-57° C. Recrystallization from aqueous methanol gave 0.58 g of pure benzyl 2-(4-benzyloxy-2,6-dimethylphenyl)acetate of melting point 62°-64° C.
