Reaction Steps

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.).
