ISSUE:

Hello, I had a question about this retrosynthesis exercise, and it concerns the organic I reactions, just to ask if this way would be correct.
thanks in advance

Hi Elena, the error you have is that you use LDA to form an enolate from an alcohol, that is not possible, first it oxidizes the alcohol to the respective ketone and now if you form the enolate and alkylate it, an alternative answer is to use the pyrrolidine to form a Stork enamine and alkylate it, which makes the reaction conditions milder
