Abstract
The present invention provides a method for producing an N-monoalkyl-3-hydroxy-3-arylpropylamine compound represented by Formula (2): wherein Ar represents an optionally substituted aryl or an optionally substituted heteroaryl, R represents an optionally substituted Calkyl, and * represents an asymmetric carbon atom; the method comprising:reacting, in the presence of an asymmetric reduction catalyst, hydrogen gas with an N-benzyl-N-monoalkyl-3-oxo-3-arylpropenylamine compound represented by Formula (1): wherein Ar and R are as defined above. The present invention allows an optically active N-monoalkyl-3-hydroxy-3-arylpropylamine compound to be produced easily and inexpensively under industrially advantageous conditions.
