Procedure

In a similar fashion, nonobutyleneglycol (3-methyl-5-t-butyl-4-hydroxyphenyl)acetate can be prepared by substituting an equivalent amount of nonobutyleneglycol for octaethyleneglycol and substituting an equivalent amount of methyl (3-methyl-5-t-butyl-4-hydroxyphenyl)acetate for methyl 3-(3',5'-di-t-butyl-4'-hydroxyphenyl)propionate in the above procedure.
