Procedure

Following the same general procedure as in Example I, 40 mmols of N,N-dimethyl-4-aminomethyl-2-methyl-6-t-butylphenol were reacted with 80 mmols of 1,3-butadiene in 81 g of toluene at about 207° C. for 10 hours. The uncorrected isolated yield of 2-methyl-4-t-butylspiro[5.5]undeca-1,4,8-trien-3-one was 83%.
