Procedure

12.8 Parts of 2,6-dichlorophenol, 14.2 parts of methyl 5-methyl-hex-5-enoate, 130 parts of 98% sulphuric acid, and 24 parts of methanol were stirred and heated on a steam-bath for 24 hours and the reaction mixture then worked up as in Example 25. Distillation gave methyl 5-(3,5-dichloro-4-hydroxyphenyl)-5-methyl-hexanoate b0.5 140°-60° C. and m.p. 101°-3° C., with the following percentage composition by weight.
