two of the start material should be react with Benzaldehyde
I think EA may be more easy
The reaction may be used base,for example Na(H,OR)?
But why you not remove methyl acetate from 1-phenyl-Ethanone?
its bp is only 57degree

Well the first step in an aldol reaction is formation of an enolate.  Which has the most acidic protons next to the carbonyl?

Well, the product has 2 benzene rings.
Now look at the reactants.

Benzaldehyde has a ring on it.... so it react with the beta-carbon and all of them connect right?
