Reaction Steps

To a mixture of 2-fluoro-6-nitro-3-pyrrolidin-1-ylaniline (285 mg, 1.26 mmol) in ethanol (20 ml) was added a slurry of Raney nickel (approximately 100 mg) in ethanol. The mixture was stirred under a hydrogen atmosphere (1 atm) at rt overnight. The reaction was purged of hydrogen, flushed with nitrogen and then filtered through a pad of Celite® using ethanol to rinse. The filtrate was concentrated under reduced pressure to afford crude product (43 mg, 17%) which was used without purification. 1H NMR (300 MHz, DMSO-d6) 6.19 (dd, J=8.4, 1.5 Hz, 1H), 5.89 (dd, J=8.4, 8.4 Hz, 1H), 4.30 (s, 2H), 4.20 (s, 2H), 2.94-3.07 (m, 4H), 1.72-1.89 (m, 4H); ES-MS m/z 196.3 (MH)+; HPLC RT (Method B) 1.08 min.
