Reaction Steps

To (1Z)-1-(3-chloro-2-methylphenyl)ethanone oxime (383 mg, 2.08 mmol) in acetic acid (10 ml) was added zinc dust (2.72 g, 41.6 mmol) and the resulting mixture was stirred at 40° C. for 3 hours. The reaction mixture was diluted with methanol and filtered. The filtrate was concentrated in vacuo and the obtained residue was partitioned between 1 N hydrochloric acid and ethyl acetate. The aqueous portion was neutralized with sodium bicarbonate and extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate and concentrated in vacuo to give 1-(3-chloro-2-methylphenyl)ethanamine as a clear oil (290 mg, 1.7 mmol, 82% yield). 1H NMR (400 MHz, CDCl3): 8.98 (s, 1H), 7.11-7.44 (m, 3H), 2.37 (s, 3H), 1.81 (s, 3H); MS (EI) for C9H12ClN: 170 (MH+).
