実験手順

Methyl (4-(6-chloro-2-benzothiazolyl)amino-3-chlorophenyl)acetate (271 mg, 0.74 mmol) was dissolved in THF (4.5 ml). To the resulting solution was added 0.5N NaOH (4.5 ml, 2.25 mmol), followed by stirring at room temperature for 15 hours. The reaction mixture was poured in ice-1N HCl. The crystals thus precipitated were collected by filtration under reduced pressure, washed with water and dried under reduced pressure to give (4-(6-chloro-2-benzothiazolyl)amino-3-chlorophenyl)acetic acid (248 mg, 95%) as a pale yellow solid.
