Abstract
A method of separating Dp-hydroxyphenylglycine from a mixture containing D- and DL-p-hydroxyphenylglycins, alkyl esters thereof having 1 to 10 carbon atoms in the alkyl group or mixtures thereof, which is characterized by: (a) forming a solution of the mixture in aqueous hydrobromic acid; (b) isolating the insoluble DL-p-hydroxyphenylglycine hydrobromide formed in step (a) of the solution; (c) adjusting a hydrobromide solution of D-p-hydroxyphenylglycine obtained from step (b) to a pH within the range of 4.0 to 6.0; and (d) isolating the resulting D-p-hydroxyphenylglycine formed from step (c) in crystalline form.
