More Information
Summary:A process for preparing an amine of the structure which comprises a. treating an aqueous solution of a keto acid of the structure with ammonium formate, nicotinamide adenine dinucleotide, dithiothreitol and partially purified phenylalanine dehydrogenase and/or formate dehydrogenase enzyme (PDH/FDH); and b. adjusting pH of the reaction mixture with sodium hydroxide to form the desired amine which is substantially free of undesirable excess ammonium ions.
