Versuchsvorschrift

70 g of 3-nitro-4-methylphenol, prepared according to German Offenalegungschrift No. 2,213,568, 200 ml of tetrahydrofuran and 2 g of activated Raney nickel catalyst were placed in a Parr bomb. The mixture was shaken for 3.5 hours under 60 p.s.i. hydrogen pressure. The mixture then was filtered and the solvent was evaporated from the filtrate. The residue was recrystallized from ether to give 3-amino-4-methylphenol (3A), as a grey solid, mp: 145°-148° C.
