Disclosed are a novel 7-(N-substituted amino)-3-oxo-2-phenylheptanoate derivative of formula(2), 7-(N-substituted amino)-3-hydroxy-2-phenylheptanoate derivative of formula(3), and 7-(N-substituted amino)-3-benzenesulfonyloxy-2-phenylheptanoate derivative of formula(4), which are quite important major intermediates of 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 of formula(5).
