実験手順

A solution of LiOH (420 mg, 10 mmol) in water (8 ml) was added to a stirred solution of methyl 5-(4-morpholinylcarbonyl)-2-[(phenylmethyl)oxy]benzoate (may be prepared as described in Description 56; 450 mg, 1.27 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), 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 crude title compound as a white solid. 400 mg.
