A process for resolution of a mixture of (R)-and (S)-enantiomers of 1-aminoindan comprising fractional crystallizing one diastereomeric acid addition salt of 1-aminoindan from a solution containing a pair of diastereomeric acid addition salts of 1-aminoindan, wherein the salt-forming acid is an optically pure chiral dicarboxylic acid selected from the group consisting of L(+)-aspartic acid, L(-)malic acid and (2R,3R)-tartaric acid, and wherein the solvent for obtaining said solution is methanol.
一种用于分离(R)-和(S)-对映体的1-氨基茚的方法,包括从含有一对1-氨基茚的两个对映异构酸盐的溶液中分数结晶一个对映异构酸盐,其中盐形成酸是选择自L(+)-天冬氨酸、L(-)-苹果酸和(2R,3R)-酒石酸的光学纯手性二羧酸,而用于获得该溶液的溶剂是甲醇。
