Reaction Steps

5-Benzyloxy-2-fluoro-4-methyl-1-nitrobenzene (500 mg, 1.9 mmol) in methanol (110 ml) was added to a suspension of Raney nickel (75 mg) and hydrazine hydrate (0.47 ml, 9.5 mmol) in methanol (10 ml) and heated at reflux. The mixture was maintained under reflux for 15 minutes and then the insoluble materials removed by filtration through diatomaceous earth. The filter pad was washed with methanol and the solvent removed from the filtrate by evaporation to give 5-benzyloxy-2-fluoro-4-methylaniline (440 mg, 99%).
