| titleOfInvention | Method for producing optically active α-methylbenzylamine |
| abstract | (57) [PROBLEMS] To control the crystal habit of a sparingly soluble diastereomer salt when optically resolving (RS) -α-methylbenzylamine in an aqueous solution using optically active mandelic acid as a resolving agent. The optically active bis (α-methylbenzyl) amine used in the above is produced as a by-product in the racemization step of the unnecessary enantiomer produced by optical resolution without adding it in a separate step and using it. To be able to This provides a process for producing optically active α-methylbenzylamine that can be carried out industrially advantageously. SOLUTION: The optically active α- Unnecessary enantiomer of methylbenzylamine is racemized in the presence of a catalytic amount of a strongly basic racemizing agent, preferably sodium hydride, and bis (α (RS) -α-methylbenzylamine containing (-methylbenzyl) amine is used as at least a part of a raw material for optical resolution, and is used together with fresh (RS) -α-methylbenzylamine in the next optical resolution step. Supply as raw material. |
