Reaction Conditions

Reaction Steps

A solution of lithium hydroxide (468 mg, 11.16 mmol) in water (25 m) was added dropwise to a stirred solution of (2-chlorophenyl)methyl 5-bromo-2-{[(2-chlorophenyl)methyl]oxy}benzoate (may be prepared as described in Description 27; 520 mg, 1.12 mmol) in THF (25 ml) over 1 min. The reaction mixture was stirred at 20° C. for 16 hours. The organic phase was evaporated and the aqueous phase (25 ml) was adjusted to pH 2 with 2M hydrochloric acid (1 ml) and was extracted by ethyl acetate (3×20 ml). The organic phase was evaporated in vacuo to yield the title compound as a light yellow solid. 350 mg.
