p-Amino-p′-hydroxybenzil was prepared from p-nitro-p′-ethoxybenzil which was converted first to p-nitro-p′-hydroxybenzil with aluminum chloride, then to a monoxime with hydroxylamine hydrochloride, reduced with ammonium sulfide to p-amino monoxime, and finally hydrolyzed to the α-diketone. p-Amino-p′-methylbenzil was obtained according to the method described in the previous report from 4′-nitro-4-methyl-desoxyben-zoin obtained by the Friedel-Crafts' condensation of p-nitrophenacetyl chloride with toluene.
