Reaction Steps

2-Formamidophenol (m.p. 129° C.) is prepared by heating 2-aminophenol and formic acid (E. Bamberger, Chem. Ber., 1903, 36, p. 2052) and is formed together with anthranil by the oxidation of 2-aminobenzaldehyde with neutral permonosulfuric acid. 2-Acetamidophenol (m.p. 201° C.) is formed by the regulated acetylation of 2-aminophenol, by dissolving 2-acetamidophenol in caustic soda solution (Bamberger, loc. cit.) or by the reduction of 2-nitrophenol with tin and acetic acid (J. B. Tingle and L. F. Williams, Amer. Chem. J., 1907, 37, p. 57).
