What product is formed in the mixed Claisen condensation between methyl benzoate and cyclohexanone?

But, here is a questions to get you started:  Where are the acidic protons on your two reagents?

From mechanism, base will attach alpha H in ketone.
Then the double bond is moved alpha C and carbonyl carbon while O become negative.

Then carbonyl carbon in ester is being attacked by alpha carbon --(nucleophilic addition)

Then OMe is a leaving group while enolate anion in ester move back to original to carbonyl carbon--(elimination)

Then only two product are formed.

MeOH + ?

(Please guess the another product!)

ok thanks, i didn't realize we had to show our work on here first, i'm new to this forum and i'm not sure exactly how to put the structures in.  anyway i really appreciate your help dolphinsiu, i was able to get the other product after you explained that.  i really appreciate everyones help.  thank you
