실험 절차

To 30.4 g (0.2 mol) of 4-dimethylaminobenzaldehyde in 100 ml of xylene, 39.1 g (0.46 mol) of piperidine is added dropwise over a period of six minutes. The mixture is heated at reflux using a Dean-Stark trap until the separation of water is complete. To the cooled reaction mixture 40.3 (0.2 mol) of 2,6-di-tert-butylphenol in 70 ml of xylene is added rapidly. The mixture is then heated at reflux for five hours. The title compound is isolated as an almost white solid by evaporation of the solvent and recrystallization from toluene-hexane. The yield is 66.3 g of the title compound, melting at 184°-185° C.
