| abstract |
A process for the preparation of the N-L- alpha -aspartyl-L-phenylalanine 1-methyl ester (aspartame) which is characterized by adding phosphoric acid and a lower alkyl alcohol to the reaction mixture containing N-formyl alpha -L-aspartyl- and beta -L-aspartyl-L-phenyl-alanine methyl ester and only one of the resultant deformylated isomers, i.e. aspartame phosphate precipitates. The alpha -isomer phosphate is collected by filtration and converted to free aspartame by treatment with a base.n[US4656304A] |
