In order to find the best method of synthesizing tuberculostearic acid, a branched-chain fatty acid contained in the lipoid of tubercle bacilli, a mixture of the lead salts of α-methyloctylacetic acid and ethyl hydrogen azelate was dry-distilled to obtain ketonic acid but the reaction was unsuccessful. Attempt was then made for the Kolbe's electrolysis of potassium α-methyloctylacetate and potassium salt of ethyl hydrogen sebacate by which a racemic acid was obtained. Acid amide of this dl-tuberculostearic acid melted at 80-81.5°.
