Versuchsvorschrift

To a stirred solution of 15 g. (0.0504 mole) of 4-(4'-aminophenyl)-2,6-di(t-butyl)phenol in 75 ml. of dichloromethane is added dropwise 5.37 g. (0.0504 mole) of n-butyroyl chloride. The reaction is immediate. The solvent is removed by evaporation, and the solid residue is recrystallized, first from aqueous ethanol, then from heptane to provide 4-(4'-butyramidophenyl)-2,6-di(t-butyl)phenol, m.p. 180°-181° C.
