Reaction Steps
To 2-methoxy-4-(2-nitro-ethyl)-phenol (2.0 g) and Raney-nickel (3.7 g) in ethanol (30 ml) is added hydrazine hydrate (3.8 g) during 30 minutes. The reaction mixture is stirred for 1 hour at room temperature. After filtration the reaction mixture is poured into water (350 ml). It is extracted with ethyl acetate (2×400 ml) washed with brine (2×50 ml) dried (Na2SO4) and evaporated. 4-(2-amino-ethyl)-2-methoxy-phenol is obtained as colorless crystals.
