摘要：

A method for producing a compound (4), which comprises allowing a compound (1) to react with hydrogen gas in an inert solvent, in the presence of a specific chiral ligand and a ruthenium catalyst, or in the presence of an asymmetric transition metal complex catalyst previously generated from the chiral ligand and the ruthenium catalyst.
