実験手順
Phenyl N-[2-(3,5-di-t-butyl-4-hydroxybenzoylamino)phenyl]carbamate (1.6 g) and dibenzylamine (0.7 g) were dissolved in benzene (10 ml) and stirred at 70°-80°0 C. for 2 hrs. The reaction solution was washed with 2N sodium hydroxide, saturated ammonium chloride solution, dried over anhydrous NaSO4 and the solvent was distilled off. Purification of the residue by a silica gel column chromatography followed by crystallization from ether afforded N-[2-(3,3-dibenzylureido )phenyl]-3,5-di-t-butyl-4-hydroxybenzamide (0.47 g, 23%).
