Abstract

4-Methylamino-2-methylphenol sulphate is prepared by reacting toluhydroquinone and sodium sulphite with methylamine followed by addition of sulphuric acid. N,N1-ethylene bis-(4-amino-2-methylphenol) is prepared by reacting N,N1-oxalyl bis(4-amino-2-methylphenol) with lithium aluminium hydride. The N,N1-oxalyl bis(4-amino-2-methylphenol) is prepared by reacting 4-amino-2-methylphenol with oxalyl chloride, 4-(b -aminoethylamino) phenol sulphate is prepared by reacting p-bromophenol with ethylenediamine in the presence of copper sulphate followed by treatment with sulphuric acid.
