{4-[(3,4-Dinitrophenyl)oxy]phenyl}methanol → HCID 57585853, compound

Participants

Reaction Steps

{4-[(3,4-dinitrophenyl)oxy]phenyl}methanol (3.73 g, 12.9 mmol) was hydrogenated in approximately 100 ml of ethyl acetate under a balloon of hydrogen over 1.2 g of 10% Pd on carbon (wet, degussa type) for 2.5 hours. An additional 600 mg of 10% Pd on carbon (wet, degussa type) was added and the reaction was hydrogenated under a balloon of hydrogen for 14.5 hours. The catalyst was filtered away and the filtrate was concentrated. The residue was dissolved in 1:1 ethanol:ethyl acetate and hydrogenated under a balloon of hydrogen over 1.2 g of 10% Pd on carbon (wet, degussa type) for 23.5 hours to consume remaining reaction intermediates. The catalyst was filtered away and the filtrate was concentrated to give 3.21 g of crude {4-[(3,4-diaminophenyl)oxy]phenyl}methanol, which was used without further purification.
