Process for producing valproic acid
摘要:
A process for making valproic acid from an alkyl alkanoylacetate is disclosed. The alkyl alkanoylacetate is reacted with an n-propyl halide in a biphasic system in the presence of a base and a phase transfer catalyst. The product mixture is acidified to convert the resulting valproate salt into valproic acid.
