Reaction Steps
16.6 Parts of 2-t-butylhydroquinone, 14.2 parts of methyl 5-methyl-hex-5 -enoate and 0.5 parts of p-toluene sulphonic acid are reacted and worked up as described for Example 25. Distillation gives methyl 5-(4'-t-butyl-2',5'-dihydroxyphenyl)-5-methyl-hexanoate, b0.3 186°-210° C. This fraction, after crystallisation from 40°-60° petroleum ether, has m.p. 136°-9° C. and the following percentage composition by weight.
