Procedure

A solution of lithium hydroxide (367 mg, 8.75 mmol) in water (20 ml) was added dropwise to a stirred solution of [4-(methyloxy)phenyl]methyl 5-bromo-2-({[4-(methyloxy)phenyl]methyl}oxy)benzoate (may be prepared as described in Description 17; 400 mg, 0.875 mmol) in THF over 1 min. The reaction mixture was stirred at 20° C. for 16 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) and was extracted with ethyl acetate (3×20 ml). The organic phase was evaporated in vacuo to yield the title compound as a light yellow solid. 200 mg.
