Versuchsvorschrift
Methyl 2-fluoro-5-methoxy-4-nitrobenzoate (549 mg; 1.13 mmol; 1 eq.) was dissolved in MeOH (50 mL). The resulting solution was injected on a flow hydrogenation reactor (H-Cube), adapted with Pd/C cartridge (44 mm), a flow of 1 mL/min, a temperature of 60° C. and the full H2 option enabled. Solvents were evaporated, affording the title product as an off-white solid (220 mg; 97%). LC/MS (Method B): 200.0 (M+H)+. HPLC (Method A) Rt 3 min (Purity: 91.9%).
