Reaction Steps

A mixture of ethyl 2-(2,4-difluoro-5-nitrophenyl)acetate (16 g, 130 mmol) and 10% Pd/C (1.6 g, 1.5 mmol) in EtOAc was hydrogenated (30 psi) at RT for 12 h. The catalyst was filtered off and the filtrate was evaporated. The residue was purified by column chromatography to give ethyl 2-(5-amino-2,4-difluorophenyl)acetate (14 g, 99% yield). 1H NMR (300 MHz, DMSO-d6): δ 6.98 (t, J=9.9 Hz, 1H), 6.70 (t, J=7.8 Hz, 1H), 4.50 (s, 2H), 4.06 (m, 2H), 3.53 (s, 2H), 1.16 (t, J=6.9 Hz, 3H); MS (ESI) m/z: 216.2 [M+H]+.
