Participants

Reaction Steps

Water (50 ml) and lithium hydroxide (0.60 g, 24.93 mmol) were added to a solution of (3,4-difluorophenyl)methyl 5-bromo-2-{[(3,4-difluorophenyl)methyl]oxy}benzoate (may be prepared by Description 88; 3.9 g, 8.31 mmol) in tetrahydrofuran (150 ml). The mixture was heated to reflux for 2 hours. The mixture was allowed to cool and diluted with ethyl acetate (200 ml) and this mixture was then acidified to pH=1 using 2M aqueous HCl. The organics were separated and the aqueous layer was extracted with ethyl acetate (100 ml). The organics were combined, dried (MgSO4) and evaporated under reduced pressure to yield the title compound as a white solid. 2.9 g. The residue contains some benzyl alcohol.
