Abstract
l-Phenylglycine, useful as raw material for medicine, was sepd. by reaction of d, l-phenylglycine with l-2-aminobutanol. Thus, d, l-acyl-phenylglycine-l-2-aminobutanol salts were prepd. by neutralizing the acylphenylglycine obtained by acylation of the phenylglycine. This salts were sepd. by crystn. and treated with acids to give l-phenylglycine by eliminating l-2-aminobutanol., and d-acylphenylglycine-l-2-aminobutanol salt was recemized and recycled.
