Reaction Steps

A solution of lithium hydroxide (328 mg, 7.83 mmol) in water (20 m) was added dropwise to a stirred solution of (2-cyanophenyl)methyl 5-bromo-2-{[(2-cyanophenyl)methyl]oxy}benzoate (may be prepared as described in Description 34; 350 mg, 0.78 mmol) in THF (20 ml) over 1 min. The reaction mixture was stirred at 20° C. for 18 h. The organic phase was evaporated and the aqueous phase (20 ml) was extracted with ethyl acetate (20 ml). The aqueous phase (20 ml) was adjusted to pH 2 with 2M hydrochloric acid (1 ml). The residual water phase was extracted with ethyl acetate (3×20 ml). The organic phase was then evaporated in vacuo to yield the title compound as a light yellow solid. 160 mg.
