Reaktionsschritte

To a stirred solution of ethyl 2-(4-(benzyloxy)phenyl)acetate (20 g, 0.07 mol) in EtOH (300 mL) was added a solution of KOH (20.7 g, 0.37 mol) in water (100 mL) at RT. The reaction mixture was then stirred for additional 1 h at RT and then concentrated in vacuo. The residue was acidified to pH˜2 using 2 N HCl and extracted with EtOAc (3×200 mL). The combined organic layers were washed with water, dried over Na2SO4, filtered, and concentrated in vacuo to afford 2-(4-(benzyloxy)phenyl)acetic acid (19 g, 98%) as a solid.
