4. Propose a synthetic pathway for the following reaction (there may be more than one correct way), then show the mechanism for each step (Hint: To save time make sure your synthesis pathway is absolutely coret before you work on mechanism) но Br
Choose the best reagent for carrying out the following reactions
from the list below. Place the letter of the reagent(s) in the box
over the reaction arrow; use only one letter per box. Some letters
may be used more than once, and not all letters need to be
used.
