Abstract
Disclosed is a 7-(N-substituted amino)-3-oxo-2-phenylheptanoate derivative, 7-(N-substituted amino)-3-hydroxy-2-phenylheptanoate derivative, and 7-(N-substituted amino)-3-benzenesulfonyloxy-2-phenylheptanoate derivative, which are quite important major intermediates for an antidepressant. The 7-(N-substituted amino)-3-oxo-2-phenylheptanoate derivative can be manufactured by condensing an enolate of phenylacetates with a 5-(N-substituted amino) pentanoate derivative.
