Hydrochloric Acid → 4-Amino-2-ethylphenol

Participants

Reaction Steps

A solution of 2-ethyl-4-nitro-phenol (3.34 g, 20.00 mmol) in MeOH (40 ml) and aqueous 1M HCl (20 ml, 20.00 mmol) was hydrogenated in the presence of 10% Pd/C (0.33 g) for 4 h. After removal of the catalyst the reaction was evaporated and suspended in CH2Cl2 and a small amount of MeOH, dried (Na2SO4) and evaporated to give 3.35 g (96%) of 4-amino-2-ethyl-phenol.HCl, MS: 138 (MH+), MP: 239-240° C., dec.
