Hydrochloric Acid → 4-Benzyloxyphenylacetic acid

Participants

Reaction Steps

A 1:2 methanol/tetrahydrofuran (60 mL) solution of (4-benzyloxy-phenyl)-acetic acid methyl ester (1.35 g, 5.27 mmol) was combined with 2M aqueous lithium hydroxide (20 mL) at room temperature and the reaction was stirred overnight. The reaction was acidified to pH 1 with 1N hydrochloric acid and extracted with ethyl acetate (2×50 mL). The organic portions were dried over sodium sulfate and the solvent removed in vacuo to give the title compound as a white crystalline solid (1.25 g, 98%). 1H NMR (300 MHz, CDCl3) δ3.63 (s, 2H), 5.09 (s, 2H), 6.96-6.99 (d, 2H), 7.22-7.25 (d, 2H), 7.3-7.5 (m, 5H).
