1-[5-(Benzyloxy)-2-nitrophenyl]-2-methyl-2-propen-1-one → 1-(2-Amino-5-hydroxyphenyl)-2-methyl-1-propanone

Participants

Reaction Steps

0.2 g of palladium/carbon (10%) is suspended in a solution of 1.34 g (4.51 mmol) of 1-[5-(benzyloxy)-2-nitrophenyl]-2-methyl-2-propen-1-one in 50 ml of ethanol. The mixture is shaken under a hydrogen atmosphere at 3 bar for 4.5 h, then the mixture is filtered off through kieselguhr, the filtrate is concentrated in vacuo and the residue is purified on silica gel (cyclohexane/ethyl acetate 5:2-1:1). 511 mg (63%) of 1-(2-amino-5-hydroxyphenyl)-2-methyl-1-propanone are obtained.
