Participants

Reaction Steps

A mixture of the [5-(4-fluoro-benzyloxy)-2-iodo-phenyl]-acetic acid methyl ester (example 20c, 3 g, 7.49 mmol) and lithium hydroxide (215 mg, 8.99 mmol) in water and THF (1:1 v:v, 40 mL) was stirred at room temperature for 2 h. The THF was evaporated and the mixture acidified to pH 3-4 with 0.1N HCl. After extraction with ethyl acetate, drying of the organic layer with magnesium sulfate, filtration and evaporation a white solid was obtained (2.9 g, 100%). MS: m/e=384.9 (M−H+).
