実験手順

6-Chloro-7-(4-(4-(trifluoromethylthio) phenethylcarbamoyl)phenoxy)chroman-4-carboxylic acid (58.7 mg, 0.106 mmol), 0.1 molar in tetrahydrofuran, was treated with sodium methanolate (213 μL, 0.106 mmol) at ambient temperature. After 20 minutes, the solvent was removed in vacuo. The resulting solid was taken up in ethyl acetate and concentrated in vacuo. The solid was taken up in 4:1 dichloromethane-hexanes and concentrated in vacuo and dried under high vacuum to provide sodium 6-chloro-7-(4-(4-(trifluoromethylthio)phenethylcarbamoyl)phenoxy)chroman-4-carboxylate (60.0 mg, 0.105 mmol, 98.3% yield) as a solid. MS (apci) m/z=552.0 (M+2H-Na).
