Reaction Steps

5.5 Parts of hydroquinone, 22.8 parts of 1,7-di-methoxycarbonyl-4-methylhept-3-ene and 1.0 parts of p-toluene sulphonic acid, are heated on a steam-bath for 3 days. After dilution with ether the reaction mixture is washed with sodium bicarbonate solution, water, evaporated and distilled to give dimethyl 5-methyl-5-(2',5'-dihydroxyphenyl)-azelate, b0.1 260°-9° C. with the following percentage composition by weight.
