実験手順
The mixture of 430 mg of methyl 3-chloro-2-cyanobenzoic acid obtained by the same manner as in U.S. Pat. No. 4,900,739, 22 ml of methanol and 2.5 ml of aqueous sodium hydroxide (1 mol/l) was stirring at room temperature for 2 hours. To the reaction mixture was added hydrochloride (5 mol/l) and was extracted with chloroform. The organic layer was washed with water and saturated brine, and then dried over magnesium sulfate. The organic layer was filtered and concentrated in vacuo to give the title compound.
