実験手順

(4-Hydroxy-phenoxy)-acetic acid methyl ester 11 (20 grams, 109.89 mmol) is added to 10% sodium hydroxide solution (100 mL) and heated to 90° C. on water bath for 6 hours. The reaction mixture is cooled to room temperature, and the pH is adjusted to 2 with distilled HCl. Crude 12, is filtered, dried, and can be recrystallised in appropriate solvent.
