Procedure

5.0 Parts of 2-methyl-4-(5-methoxycarbonyl-2-methyl-pent-2-yl)-phenol, 2.4 parts of α-methylstyrene, and 0.5 parts of 70% perchloric acid in 25 parts of methylene chloride were reacted and worked up as described in Example 61. Distillation gave methyl 5-(3-cumyl-4-hydroxy-5-methyl-phenyl)5-methyl-hexanoate, b0.7 210°-4° C. as an oil with the following percentage composition by weight.
