Abstract
1374350 Amide DYNAMIT NOBEL AG 15 Dec 1972 [18 Dec 1971] 58199/72 Heading C2C An enantiomorph of N-benzoyl-[α-amino phenylacetic acid] is selectively crystallized out of a supersaturated solution of N-benzoyl- [DL-α-aminophenylacetic acid] containing the enantiomorph dissolved therein and/or in the form of seed crystals. The enantiomorph may be converted to the corresponding enantiomorph of α-aminophenylacetic acid.
