# Retrosynthesis of spirocyclic compounds?

I have been trying to complete this retrosynthesis problem for a few days but can’t figure out how to get from Ester starting compound to a spirocyclic compound. I have tried removing the Ester but can’t figure out what best to replace it with. I have access to any reagents and starting materials as long as the nominated substance is used.

Step 1 - Form the anion of your starting material ($$\ce{NaOEt/EtOH}$$ will do this nicely) and react with phenethyl bromide ($$\ce{PhCH2CH2Br}$$).
Step 2 - Add the product to hot polyphosphoric acid$$\ce{^{[1]}}$$ to cyclize it to the required product.
