Participants

Reaction Steps

Ethyl 8-[4-(2-butoxyethoxy)phenyl]-3,4-dihydro-1-benzoxocin-5-carboxylate (527 mg) was dissolved in THF (40 ml) and methanol (40 ml). Aqueous 1N sodium hydroxide solution (12.4 ml) was added to the solution and the resulting solution was stirred overnight. After neutralization with 1N hydrochloric acid at 0° C., the solution was extracted with ethyl acetate. The organic layer was washed with saturated saline and dried over magnesium sulfate. The solvent was distilled off under reduced pressure and the residue was recrystallized from hexane-ethyl acetate to obtain colorless crystals of 8-[4-(2-butoxyethoxy)phenyl]-3,4-dihydro-2H-1-benzoxocin-5-carboxylic acid (160 mg).
