甲基 2,3-二氨基-5-氟苯甲酸甲酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A slurry of 2-amino-5-fluoro-3-nitro-benzoic acid methyl ester (1.8 g, 84.0 mmol) and 10% Pd/C (0.5 g) in methanol (50 mL) was hydrogenated with a hydrogen balloon for 2 h. After completion of the reaction, the reaction mixture was filtered over celite bed, concentrated to dryness. the resulting residue was purified by column chromatography using 30% ethyl acetate in hexane to obtain the title compound as off white solid. After completion of the reaction the reaction mixture was filtered over celite bed concentrated to dryness the resulting residue was purified by column chromatography
