Procedure
7-(4-(2-(benzo[d][1,3]dioxol-5-yl)ethylcarbamoyl)phenoxy)-6-chlorochroman-4-carboxylic acid (60 mg, 0.12 mmol), 0.1 molar in 4:1 tetrahydrofuran-methanol, was treated with sodium methanolate (242 μl, 0.12 mmol) at ambient temperature. After 15 minutes, the solvent was removed in vacuo. The resulting solid was taken up in ethyl acetate and concentrated in vacuo. The solid was then taken up in 4:1 dichloromethane-hexanes and concentrated in vacuo and dried under high vacuum to provide sodium 7-(4-(2-(benzo[d][1,3]dioxol-5-yl)ethylcarbamoyl)phenoxy)-6-chlorochroman-4-carboxylate (63 mg, 0.12 mmol, 101% yield) as a solid. MS (apci) m/z=495.9 (M+2H-Na).
