반응 단계
Following the same general procedure as in Example I, 20 mmols of N,N-dimethyl-4-aminomethyl-2,6-di-t-butylphenol were reacted with approximately 222 mmols of 1,3-butadiene in 47 g of ethyl acetate at about 190° C. for 10 hours. As determined by GC analysis, the process resulted in a 100% yield of 2,4-di-t-butylspiro[5.5]undeca-1,4,8-trien-3-one.
