反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A solution of methyl 4-hydroxybenzoate in DMF (5 ml) was treated with K2CO3 (2.76, 20 mmol) and 2-benzyloxy benzyl bromide (1.52 g, 10 mmol). The reaction was stirred at ambient temperature over night. The reaction mixture was partitioned between ethyl acetate and water and the organic phase was washed well with water dried (MgSO4) and evaporated. The crude material was purified by chromatography [EtOAc:hexane] to give methyl 4-(2-(benzyloxy)benzyloxy)benzoate as a white solid (3.06 g, 88%). The reaction mixture was partitioned between ethyl acetate and water the organic phase was washed well with water dried (MgSO4) evaporated The crude material was purified by chromatography [EtOAc:hexane]

反応条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Sodium hydride (6.5 g, 50% dispersion in oil) in DMF (100 ml) was cooled (0° C., ice bath) and 4-thiobenzoic acid (10 g) was added. After stirring for 30 minutes at 0° C., 2-bromomethylphenyl benzyl ether (18.6 g) as a solution in DMF (100 ml) was added. The reaction was stirred at ambient temperature for 18 hours, cooled (ice bath), water was added, and the mixture acidified with acetic acid. The resulting solid was isolated by filtration and recrystallised from methanol to give 4-[2-benzyloxybenzylthio]benzoic acid (24 g) (mpt. 144° C.). was added The reaction was stirred at ambient temperature for 18 hours was added The resulting solid was isolated by filtration recrystallised from methanol
