My study group and I have been stuck on this problem for awhile now, and I don't know what else to try. I can do the wittig reaction but then I don't get how to acid catalyze the wittig Product. Usually with Acid Catalyzed Hydration there is a proton transfer then Nuc Attack but I don't see how that can happen in what I am given. I have attached pictures of the problem and my most recent work to the problem.
Thanks for taking the time to assist
