실험 절차

The similar procedure in reference example 1 by using 12.2 g of 2-chloro-4,6-dimethylnicotinoyl chloride, 14.8 g of 2,6-di-tertiary butylphenol and 18.8 g of anhydrous stannic chloride in dichloroethane is performed and the obtained crude product is recrystallized from hexane to give 18.3 g of 4-(2-chloro-4,6-dimethylnicotinoyl)-2,6-di-tertiary butylphenol as pale yellow crystals, melting at 129°-132° C. According to the similar manner as the above Reference Examples, 4-(2-chloro-6-isopropylnicotinoyl)-2,6-di-tertiary butylphenol, melting at 109°-110° C. is prepared.
