Versuchsvorschrift
A solution of 86.8 g of 2-chloro-4-nitrophenol in 200 ml of tetrahydrofuran containing 2 g of Raney nickel catalyst was hydrogenated in a Parr shaker at 50 p.s.i. hydrogen pressure. The mixture was filtered and the solvent was evaporated from the filtrate. The residue was recrystallized from ether to give 4-amino-2-chlorophenol (1A), as a tan solid, mp: 144°-147° C.
