D-Psicose → Methyl 4-amino-2-fluoro-5-methoxybenzoate

Participants

Reaction Steps

To a solution of 0.92 g (4.01 mmole) of 2-fluoro-5-methoxy-4-nitro-benzoic acid methyl ester and 30 mL of ethanol was added 0.10 g of 10% Pd/C. The mixture was hydrogenated in a Parr hydrogenator at 50 Psi for 1 day. The catalyst was removed by filtration and the solution was concentrated under reduced pressure to give 0.78 g of 4-amino-2-fluoro-5-methoxy-benzoic acid methyl ester.
