The present invention has an object to provide a process for easily producing optically active N-aryl-1-amino-2-propanol derivatives which are of value as pharmaceutical intermediates from inexpensive starting materials.
The above object can be attained by producing an optically active N-aryl-1-amino-2-propanol derivative by the process which comprises reacting an optically active lactate derivative or an optically active lactic acid acetal derivative, which are available at low cost, with an arylamine derivative to give an optically active N-aryllactamide derivative and treating it with a reducing agent.
Compounds having the formula
R5O—A—NR4—R2 (V)
where R2 is a heteroaryl group linked to the remainder of the molecule via a carbon atom adjacent a nitrogen atom and R4 and R5 are both hydrogen atoms or together represent —SO— or —SO2— and A is C2-C4 alkylene optionally substituted by one or more lower alkyl groups are novel intermediates in the preparation of pharmaceutically useful piperazine derivatives as end compounds. The compounds having formula V where R4 and R5 are hydrogen may be prepared by a rearrangement of a compound having the formula (VI).
R2O—A—NH2 (VI)
