実験手順

A solution 4-benzyloxy-benzoic acid methyl ester (3) (1 equi.) and potassium hydroxide (3.5 equi.) in water-ethanol (1:1) (25 mL/mmole) was stirred at 80 C temperature for 2 h., cooled to room temperature, quenched with hydrochloric acid (5%). The resulting white solid was filtered, washed with water, and dried under vacuum to give 4-benzyloxy-benzoic acid (4)) as a white solid (80%).

後処理

  1. customquenched with hydrochloric acid (5%)
  2. filtrationThe resulting white solid was filtered
  3. washwashed with water
