Abstract
The synthetic method of 3-methylheptanoic acid was improved,which crotonic acid reacted with sec-butyl alcohol to protect its carbonyl group,then reacted with n-butylmagnesium bromide,so that the sec-butyl 3-methylheptanoate was obtained.The latter was hydrolyzed under alkali to get the final product 3-methylheptanoic acid.The method was novel and the product was highly pure.The intermediates’and product’s structure were characterized by 1H NMR and IR.
