From the choices provided below, list the reagent(s) in order that will bring about the following transformation in good yield. List your answer as a letter (single-step transformation) or series of letters (multi-step transformation) in the order the reagents are used, with no commas separating them. No more than four steps are required for this synthesis. For example "gfh" corresponds to: 1. HCl, H2O 2. Mg, ether 3. CO2 NOTE: The order you in which you list your letters matters! Reagents:
