One-pot method to synthesize 4,6-bis(isopropylamino)resorcinol through hydrodechlorination and catalytically reductive mono-N-alkylation

Abstract

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