A solution of LiOH (585 mg, 13.95 mmol) in water (8 ml) was added to a stirred solution of methyl 5-[(dimethylamino)carbonyl]-2-[(phenylmethyl)oxy]benzoate (may be prepared as described in Description 58; 437 mg, 1.40 mmol) in tetrahydrofuran (2 ml) at room temperature. The mixture was stirred at room temperature for 3 h. The mixture was acidified with HCl (6 mol/l) and extracted with ethyl acetate (3×40 ml). The organic phase was washed with saturated brine (25 ml), dried over sodium sulfate, and evaporated in vacuo to give the crude product as a white solid. 350 mg.
