4-Hydroxydiphenylamine (m.p. 70° C., b.p. 330° C.) is formed by heating hydroquinone with aniline and zinc chloride at 180°-185° C. (G. Heller, Ann., 1919, 418, p. 265; A. Calm and M. Phillip, Chem. Ber., 1883, 16, p. 1799; 1884, 17, p. 2431), or by reaction of p-aminophenol with bromobenzene and cuprous iodide (German Pat. No. 187,870). 4-Amino-2-nitrophenol (dark red plates, m.p. 128° C.) can be prepared by the procedure described in A. Girard, Bull. Soc. Chim. Fr., 1924, 35, p. 773) and 4-Amino-3-nitrophenol (m.p. 154° C.), can be formed from the nitration of 4-aminophenyl acetate as described in (Girard, loc. cit.);
