Abstract
Abstract 2-Chloro-4,6-dinitrobenzene-1,3-diol was catalytically converted to the corresponding N -alkyl secondary aminophenol, 4,6-bis(isopropylamino)benzene-1,3-diol, in high yield by one-pot operation using acetone as alkyl source and hydrogen as reducing reagent over the 10%Pd/C catalyst. The effects of reaction conditions such as the amount of acetic acid, acetone concentration, hydrogen pressure, catalyst amount, and reaction time on the selectivity for 4,6-bis(isopropylamino)benzene-1,3-diol were investigated.
