To a solution of methyl 4-chloro-2-(2-ethoxy-2-oxoethoxy)benzoate (10 g, 36.67 mmol) in methanol (250 mL) and water (50 mL) was added potassium hydroxide (4 g, 71.43 mmol). After stirring for 1.5 h at 25° C., the resulting mixture was concentrated under vacuum, dissolved in water (50 mL), adjusted to pH 6 with HCl (3N) and filtered to give 2-(carboxymethoxy)-4-chlorobenzoic acid as a white solid (7 g, 80%).
