2-Bromo-4-chloro-6-nitrophenol → 2-Amino-6-bromo-4-chlorophenol

Participants

Reaction Steps

A solution of 2-bromo-4-chloro-6-nitro-phenol (16.27 g, 64.4 mM) in ethyl acetate (160 ml) was hydrogenated, at room temperature, with Raney-nickel (6 g). After hydrogen uptake (approx. 4.8 1) was complete, the nickel was removed by filtration and the filtrate evaporated in-vacuo to give 14.19 g (99.0%) of the title compound which was suitable for the next step.
