The easiest answer to any synthesis question is "just buy it"* But that tends to earn you the title of "smartass" from your proff without any credit to go with it, or "lazy cash waster" from your PI if you're a grad student.
But seriously, you have a tendency to greatly over-think organic chem problems. Some tips:
1) If its after the first week of organic chem, you will never, ever, ever see radical halogenation with UV light again (I know, AIBN-initiated reactions or the calculation of rate laws are different stories) but if you find yourself writing "Br2 + UV", you're starting to write fiction.
2) When in doubt: carbonyl chemistry. I don't know if its the most versatile functional group known, but its waaaaaaaay up there.
