A solution of 15 g. (0.050 mole) of 4-(4'-aminophenyl)-2,6-di(t-butyl)phenol in 100 ml. of glacial acetic acid is treated with 5.2 g. (0.050 mole) of acetic anhydride. The resulting solution is heated gently for 10 minutes, diluted with water, cooled, and the solid product is separated by filtration. Recrystallization from a benzene-hexane mixture provides 4-(4'-acetamidophenyl)-2,6-di(t-butyl)phenol, m.p. 173°-174.5° C.
