To a stirred solution of ethyl 2-(4-(quinolin-2-ylmethoxy)phenyl)acetate (20 g, 0.05 mol) in MeOH (200 mL), a solution of KOH (12.6 g, 0.22 mol) in water (50 mL) was added dropwise and the reaction mixture was stirred for 1 h at RT. The methanol was then removed and the reaction mixture was washed with EtOAc (2×100 mL) and acidified to pH˜3 with 1 N HCl at 0° C. The precipitated solid was then filtered and dried to afford 2-(4-(quinolin-2-ylmethoxy)phenyl)acetic acid (15 g, 92%) as a white solid.
