There is disclosed an N-(α-alkylbenzylidene)-α-phenylalkylamine represented by the general formula (1): STR1 wherein R1 represents a lower alkyl group, R2 represents a hydrogen atom, a halogen atom, a lower alkyl group or a lower alkoxy group and X represents a halogen atom or a lower alkoxy group, its use and a process for producing the same and processes for producing intermediates therefor.
Process for racemization of optically active 1-phenylethylamine derivative
-
, (2008/06/13)
A process for racemization of an optically active 1-phenylethylamine derivative represented by formula (I): STR1 wherein R1 represents a phenyl group substituted at least at the ortho-position, which comprises reacting the optically active 1-phenylethylamine derivative (1) with an aldehyde compound represented by formula (2): where R2 represents an optionally substituted alkyl group or an optionally substituted phenyl group to form an optically active imine represented by formula (3): STR2 reacting the imine with an alkaline metal tert-alkoxide in an aprotic solvent, and then hydrolyzing the resultant racemic imine.
