Reaction Steps
10% Palladium on carbon (200 mg) was added to a solution of 2-(3-fluoro-4-nitro-phenoxy)-2-methyl-propionic acid ethyl ester (1.15 g, 4 mmol) in ethanol (20 ml). The suspension was hydrogenated at a hydrogen gas pressure of 1.7 bar for 8 h at ambient temperature. Ethyl acetate was added (100 ml), the solid was filtered off and the filtrate was brought to dryness under reduced pressure to give the title compound (1.23 g, quant.) which was used in the next step without further purification.
